I have to agree that some meds (drugs is actually what they are) have bad long-term side effects and aren't healthy at all really. I refuse to take some medications because of the damage they can do on the body. I like Lamictal because so far I have zero side-effects beyond increased thirst and dehydration. I just drink extra water. Even this relatively mild drug though could cause problems long-term.
My doctor says it is a risk/reward thing. It is better to be medicated with some side-effects to health rather than to be deeply depressed, psychotic or even dead from suicide.
