What are the symptoms of caffeine withdrawal?

Regular caffeine consumption reduces sensitivity to caffeine. When caffeine intake is reduced, the body becomes oversensitive to adenosine. In response to this oversensitiveness, blood pressure drops dramatically, causing an excess of blood in the head (though not necessarily on the brain), leading to a headache.

This headache, well known among coffee drinkers, usually lasts from one to five days, and can be alleviated with analgesics such as aspirin. It is also alleviated with caffeine intake (in fact several analgesics contain caffeine dosages).

Often, people who are reducing caffeine intake report being irritable, unable to work, nervous, restless, and feeling sleepy, as well as having a headache. In extreme cases, nausea and vomiting has also been reported.

Hello again, glad your bloods

Hello again, glad your bloods were ok, I hope the lack of lemon water helps. I haven't actually been drinking lemon water, only using instead of vinegar but I have been doing that for many years pre my caffeine wd fatigue, so I don't think there is a connection but will try not using it for a few days to see.


Negative side effects reported using too much lemon water over a prolonged period of time include vomiting, lethargy, extreme weakness, and fainting. I did a search for "Dangers of lemon water detox" to find articles on this. Considering that my 1st episode of fatigue happened 4 months before I stopped drinking caffeine, but 5 months after I started drinking 2 glasses of lemon water every morning when I wake up, there's a possibility that lemon water is actually stopping me from recovering from my caffeine withdrawal. I've been drinking lemon water for close to a year now. I'm sure everyone is different and I can't say for sure this will cure my feeling of weakness and fatigue, but I am going to give it a try. I'll report back here how things turn out.

In the mean time, I did go to the doctor this week and he ran a full set of blood tests and everything came back normal. I'm supposed to go back in two week for a follow up appointment.

@ 60 Year Habit: I know you've been drinking lemon water for a long time now. Because of this, I made a special point to share this information on this board. It may help you. It may not. It's just another angle to consider.

Well that sounds more hopeful

Well that sounds more hopeful to me, as if you may have found the answer to your fatigue. If you are anything like me, it will take you more than a year though….

I am still getting phases of having the shakes and sweating too, plus dreadful backache, and a lot of insomnia. i was amazed to find that caffeine wd was stopping me sleep!

I have noticed a very slight improvement, not much, of my level of fatigue, although my muscles are gradually getting stronger and I can walk further and faster. (I have had a few short periods of a week or so when the fatigue has improved, but not for ages).

I hope somebody with a similar experience to yours chimes in soon, that would really help you.

Thank you again, for your

Thank you again, for your reply! :)

Did you have issues with tiredness/fatigue and the blood sugar/shakes before quitting coffee? Or only through your withdrawal symptoms?

No I didn't have those issues

No I didn't have those issues but I did have depression, and I haven't had a day of depression since I stopped drinking caffeine.

In fact I had a sort of manic energy all the time which I now know was related to caffeine, and I used to walk so fast none of my friends could keep up with me.

Did you have any withdrawal

Did you have any withdrawal symptoms at all? If not I would doubt it is the coffee, except it is strange about the timing being so coincidental.

I think the only way of finding out is to stay off for much longer, I have been off for over a year and still have severe fatigue, and I have read a book by someone who still had the fatigue after over 2 years of being caffeine free. although it did eventually stop. It apparently takes about 3 years for all the caffeine to leave your body.

Thanks for the reply. I did

Thanks for the reply.

I did have withdrawl symptoms, mostly headaches for a good 4-5 days. I'm already exhausted so it's hard to tell if I was any more tired or not. Lack of caffeine in my system is also doing a number of my blood sugar, too. Cravings for junk if I don't get my cup in followed by my blood sugar dropping and getting the shakes. Not sure if the shakes are lack of no coffee, same with sweating.

I just would have thought being off it for almost a half a year would have shown me something. Looks like I'm going back off it for at least a year, now.

Caffeine causing my fatigue?

Hello all,

I have been reading through most of these posts and I cannot help be notice a trend in the way people feel while having their favorite drink. Mine, is Coffee. Anywhere from 4-10 cups a day for the past 9 years. I write because for the past 8 of those 9 years, my body has been in a constant state of tiredness. NO matter how much I sleep, I always feel exhausted. I have been to every doctor known to man, and spent Tens of thousands of dollars on co-pays, prescriptions, out of network visits, and holistic testing. You name the issue, I have tried it and and the drug that combats it. My only symptom, is fatigue/daytime sleepiness. I have had two sleep studies to rule out sleep apnea and narcolepsy.

I quit coffee/caffeine for about 5 months before and never felt any better, however I'm wondering if I didn't give my cleanse long enough for my body to recover. I can drink coffee and loads of it before bed and fall right to sleep, but I often wake and have crazy dreams through out the night.

Anyone else here like me? Anyone else recover from this?

I am sorry you are feeling

I am sorry you are feeling bad again, but it is just part of the recovery pattern, although it seems a little strange to have such a big setback after feeling well for ages.

Good idea to get yourself checked out, not so good the adrenal support supplement. How do you know your adrenals are the problem, if it is just caffeine wd, time is the only cure.

I treated my "adrenal problem" with a high protein diet and only got high iron from it, it didn't help my fatigue.

I have checked my ferritin levels on the web and they are at the extremely high end of the normal range, and not in the optimal range, so I have done myself no favours with the diet at all, and I suspect it would be the same with a supplement.


I feel absolutely terrible today. Absolute total fatigue and loss of appetite. A co-worker went to the store for me and bought me a blood glucose monitoring system in case it was low blood sugar. It wasn't low blood sugar. My coworkers were concerned and said I looked so pale. :( I felt like just collapsing to the floor. I've made a doctor's appointment, but they couldn't get me in until tomorrow. I'm not expecting that they'll find anything, but I've got to try something.

I'm just disappointed. After 60 days, I was doing so well. I had several 100% days and was feeling pretty optimistic. Hopefully temporary set backs are normal. I'm having these gloom and doom thoughts again.

Hopefully tomorrow will be better.

Good news is that a coworker who just started overheard my conversation and said that he had experienced the same type of thing. He started taking something that you can buy over the counter supplement to help his adrenal glands, but couldn't remember the name of it. He will let me know tomorrow. Likewise, I'll post on here what it is.
