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
