I was on multiple psych-drugs a few years ago, and let me tell you; It was not a pleasant experience. Celexa for depression, Paxil for anxiety and a Ritalin 'Alternative' for 'ADD'. Of course, I was never on multiple psych drugs at one time, but even then, I still had vivid hallucinations and 'locked-in' dreams(nightmares that I knew where I was dreaming, but could not wake up).
Even today, I still experience those effects, even though I am no longer taking any drugs whatsoever. Though not as often, I still experience them. I highly suggest not drugging your child because they are hyper, etc, etc.
Out of curiosity, notwithstanding the side effects, did the drugs help you?
Depression and Anxiety, two sides of the same coin, are complex illnesses, and can not be treated with a one-size-fits-all approach. Whether drugs, talk therapy, hospitalization, or some combination of these is the best solution depends upon the individual being treated. That being said, I don't think anti-depressants should be prescribed for children.
Ritalin is neither good nor bad. Is it over-prescribed? Probably. Can it be misused? Definitely! The same can be said about just about any medication on the market. The emphasis scienos place on ritalin is, to me, comic. The case could be made that refined sugar is of equal danger, and is a "gateway drug".
