Studies on the side-effects of caffeine.

OAKLAND, California (UPI) -- Coffee may be good for life. A major study has found fewer suicides among coffee drinkers than those who abstained from the hot black brew.

The study of nearly 130,000 Northern California residents and the records of 4,500 who have died looked at the effects of coffee and tea on mortality.

Cardiologist Arthur Klatsky said of the surprising results, ``This is not a fluke finding because our study was very large, involved a multiracial population, men, women, and examined closely numerous factors related to mortality such as alcohol consumption and smoking.''

The unique survey also found no link between coffee consumption and death risk. And it confirmed a ``weak'' connection of coffee or tea to heart attack risk -- but not to other cardiovascular conditions such as stroke.

The study was conducted by the health maintenance organization Kaiser Permanente and was reported Wednesday in the Annals of Epidemiology.

caffeine can be dangerous

In your statement you said how you had constant fatigue and many other strange symptoms. Could you please, let me know what some of your other strange symptoms were,thank you.

fatigue and coffee

I can't believe I finally found someone else who senses that too much caffeine is causing chronic fatigue. I have been tired all day - daily - for years, drinking coffee all day long to try to pick myself up. I recently had a bout of nausea and stomach problems and stopped drinking coffee for a few days, guess what - I have more energy than I have had in years. This is the first article in all my research to corroborate what I feel has happened.

caffeine as a cause of fatigue

Very interesting to see these experiences, as I have looked around unsucessfully for references to this, in the last few months. In my case, I needed in Autumn 2006 to eliminate all caffeine when I became a subject in a drugs trial. After 6 -7 days, I experienced an unexpected improvement in energy which, at first, I felt might be due to the drug. However the improvement lasted well beyond the last dose, and has continued now for 4 months. Needless to say, I have maintained abstinence from caffeine. My consumption was mainly tea and chocolate, not in themselves all that high in caffeine, but I suspect that occasional heavy coffee drinking over 35 years ago (1970/71) might have been the trigger. Almost inevitably my original diagnosis was depression, with attendant medication, which I took for 17 years. At intervals in later years I sought medical tests in case there was a detectable physical cause. I had occasionally tried reducing tea drinking, but never before tried complete caffeine elimination. If there are yet others with this experience (or indeed those with fatigue who try caffeine elimination and report back) then maybe this could help medical knowledge and give more people their lives back.

Thank you, I've found an answer to my problems!

I am currently drinking my usual 2ltr bottle of diet coke whilst studying and as I found that my concentration level has deteriorated, I thought i may look at the effects of caffeine (as I'm shaking a little too!).

I get through my working day by drinking Diet Coke and taking Pro-Plus (Caffeine Tablets) because i just can't stay awake! I involuntary fall asleep at my desk at around 11am and at 3pm (it's so embarrassing! Everyone thinks I have a sleeping disorder) and sometimes even the caffeine doesn't help. I have been to the doctors for blood tests because my chronic fatigue is driving me mad and I can't function properly. Even at weekends I nap in the afternoon if I'm in the house because I feel so tired. I also suffer with stomach ache which I thought was my irritable bowel syndrome. I always knew the diet coke wasn't helping but not because of the caffeine but because of the gas. I also thought that i needed the Diet Coke to stay awake and thats why I continued to drink it.

I'm definitely going to try to stop drinking Diet Coke now - I really hope i see a difference quickly. I will write back and let you know how I get on.

Other factors to consider that causes fatigue

After disussing fatigue with my doctor and experiencing chronic fatigue. Coffee is like an upper, it helps you wake up, but as soon as it goes through your system, you come down again. If you drink coffee at all, it's best to just have a few sips at a time instead of cups at a time.
I became aware I have a vitamin B deficiency. Also when I take sugar completely out of my diet, I experience a onset of fatigue and sleepyness - can't stay a wake at my desk and just want to lay down and close my eyes. I've found what helps me is a combination of things (all important)
1. Eat a healthy diet of protein, colorful veggies - carrots, broccoli, peppers, fruit, and fish, etc.
2. Make sure you get a good nights sleep - if there is a problem - go see your doctor
3. Drink at least 6-8 glasses of water a day.
4. Exercise - even if you don't have time for more than 15 minutes a day. - JUST DO IT! I can be so tired I don't feel like working out, but then I'll just do some stretching exercises, not hard at all, and that gets me going. Before you know it, it has made me feel better and I've been able to work out 30 minutes.
5. Take liquid vitamin suppliments ( my chiropractor recommended "Waiora") and extra omega 3 and vitamin C.
6. If you do get a low/sleeping time during the day. Keep some celery and almonds on hand. If you have problems with fatigue because of low blood sugar - drink a glass of apple juice.
7. Cut down on salt - people don't realize how much this makes them have water retention.
If I eat too much salt - I feel terrible the next day, it causes, fatigue, headaches, ear aches, and weight gain.

I have also researched these topics as well.

It's amazing how good you will feel if you try this for a couple of weeks. After 6 months of doing all the above, i feel more alive than I ever have in my life. I first starting doing this at age 38 and when I turned 40, I was a size 3 and felt the best I've ever felt in my entire life.

Just focus on the results and don't give up.
It's worth it.

Thank you for your encouragement

I am hoping you are right. I am in serious caffeine withdrawl right now after a habit that climbed to 80-100 oz of caffenated beverages daily (mostly Diet Pepsi and coffee.) I know it couldn't have been healthy for me, but I am so exhausted, can't concentrate, and have such a bad headache that I'm reconsidering. How long do these symptoms last and when does my energy return?

my ballsack hurts and i

my ballsack hurts and i absoultely know its caused by coffee. actually tea and sodas are the reason for the tingling around the nuts.. i think the quiver in my penis is due to the coffee... bc you know.. any and ever problem or any sort can possibly be from CAFFIENEEEEE

Ex-caffeine addict =D

It took me almost a full week to stop feeling withdrawal symptoms after giving up my daily two cups of coffee, so I would expect it would take you about that long. Probably an extra couple of days, actually, since your caffeine intake was much higher than mine.

After the headaches and everything wore off, I felt incredible. It was awesome. I'm not strictly no-caffeine, but I don't have a regular daily habit anymore. If I'm at a fast food place or something, I only take caffeine content of soda into account if it's late evening, etc.

As a warning, though: I seem to have developed an over-sensitivity to caffeine now. It keeps me from sleeping much worse than it did before I ever started drinking coffee, and it's diuretic effect is stronger on me than any of my friends also. I'm not sure if the coffee or giving up of coffee caused it, but it developed around that time, so watch out. (The exaggerated effect caffeine now has on keeping me awake comes in mighty handy for pulling all-nighters writing term papers, though, so I won't say it's all bad.)

Coffee is BAD NEWS.

Coffee is BAD NEWS. I haven't had any coffee for the past 3 years and decided I missed it and drank some. My body has no tolerance at all to coffee, I'm nauseated, and have a huge headache and am extremely tired. It caused my heart to race and I had to keep myself busy trying not to think about it or I thought I was going to have a panic attack. The taste is good, but NOT worth what I just went through.

effects of caffeine

I, too, have developed a higher intolerance to caffeine since I quit it all together. Even a small cup of de-caf now gives me a headache and stomach problems. Does anyone know of an antedote to caffeine, something one can take to counter the effects of caffeine? I really like coffee and tea but can't tolerate even the smallest amounts of the stuff.
