I don't want to sound like I'm judging use of prozac. I know it's good for some people but I also think the docs tend to over-prescribe SSRI drugs like prozac. I took it for a week and it did not calm me down. It actually caused a lot of excess energy and anxiety in me. For some people who are depressed, that extra energy is a good thing, but it was not good for me. I know of others who had a similar reaction. I also know of people who swear by it (for instance, my GP takes it).
