You are right in assuming that there is a problem. The headaches, sweating, and hypermotility can all be due to the medication. You need an adjustment. Prozac is in a family of antidepressants, and you need to switch to one of it's cousins, like Paxil. Prozac is designed to give you energy, for patients who sleep too much as a result of their depression. It's allied antidepressants do not do that. You need to see your doctor and get changed over. I am a Clinical Psychologist and a life-long depression and anxiety sufferer. I also tried Prozac, and found the increased energy aggravated my anxiety. I switcheed to another SSRI antidepressant, Paxil. rar1951
