I started taking Prozac about a month and a half ago, 20 mg, the reason that I started taking it was more for anxiety than depression. All I wanted to do was sleep. I get bug crawling sensations, cold water feelings in my legs, back and face, this is the reason the doc put me on it in the first place, well, after taking it for a month, I was still sleeping to much, and the bug crawling sensations got extremely worse, doc upped it to 40 mg, now I have tremors, and the cold feelings are awful, my legs will jump for no reason. Do you think that its the Prozac causing these worsening of symptoms, if it is, would it be safe to say that it was anxiety in the first place, rather than anything else serious? (MS) I have had brain, c-spine MRI, and lumbar MRI, nothing shows but a bulging disk in my neck. I do suffer from migraines, wondering if these weird feelings could be due to migraines, anxiety, or MS? I'm so upset over this. I taken Prozac in the past, 20 mg, it never took the feelings away, but at least it helped me concentrate on things better, I wasn't sitting around worrying about stuff, and it gave me lots of energy. What do you think? Thanks
