Coffee and Caffeine FAQ

I have no doubt that at some levels, caffeine can cause mental problems and heart attacks, but I have to wonder about you guys experiencing panic and hallucinations at low levels and levels you're normally fine with. Isn't it possible that something other than caffeine is triggering this? Or if these symptoms stop when the caffeine intake ceases, couldn't it be that caffeine just lowers the threshold of an already present predisposition to these problems? Of course you shouldn't be drinking coffee or energy drinks if it makes you feel unwell, but I'm not sure if caffeine can be simply slapped on as the sole mechanism by which these events are happening, case closed. You have to look at other possibilities, and if there's also an underlying predisposition for nervousness or hallucinating, you should probably see a doctor. It might be triggered by something other than caffeine next time - stress, loss, change, who knows.

I myself am a heavy coffee drinker, and I'm mostly on this site because I know too much of anything can be bad, so I wanted the facts.
