Re: caffeine must make depression worse
I stopped taking caffeine (soda) abruptly a few years ago and haven't tried it with any anti-depressant, so I can't comment on the effects, but what most people don't realize is that caffeine can be a dangerous drug.
Scientifically, caffeine is a stimulant, in the same class of drugs as amphetamine, methamphetamine, cocaine, etc.. and it has been linked to mental illnesses (I don't think I'm allowed to post links to studies? Use Google).
It causes you to lower your inhibitions and.. basically does the same thing most other stimulants do, but on a much smaller scale (depending on the dose).
In fact, in low doses, caffeine is very similar to low doses of cocaine.. all these drugs affect your brain chemicals, so it's not far fetched that it would have an affect on your medication or mental state.
Like most everything else, keep it in moderation or don't take it at all, 'cause the stuff ain't good for neither your body, nor mind.
