Medications do work differently for evry person. Psychoactive medications are even more unpredictable because we don't know everything there is to know about brain chemistry. Everyone should be careful with whatever medication they may take, and READ the stuff the doctor or pharmacist gives you.

I have never had a medication that did not come with a list of possible side effects, and a list of ones to call the doctor about if they occur - and I'm just taking asthma medication, which is a lot better understood than the human brain.
