Some people certainly are helped by drugs but I think that they are a small minority. I took many psych drugs but they never worked well for me and the side effects and withdrawal nearly killed me.

My philosophy is to use whatever works but I think that it's best to try to find the root cause of the illness and try to use drugs only for short term treatment. Of course in mainstream medicine drugs are prescribed for years and doctors rarely look for the causes of illnesses. Most sick people stay sick.
