So 11 days on zyrem, I 've been titrating up. Right now I'm at 3.5 ml. I feel more tired during the day (started after the first night), extreme muscle pain (especially in my back), bad dreams, sweat like a pig all day long (just dripping and I live in cold WI). I also have dandruff and an itchy scalp. I sleep about 6-7 hours. Will some of these disappear after time? I've been at 3.5 * 2 for 5 days now and it's getting worse. Thanks everyone. Also, what other drugs increase stage 3 & 4 with few side effects?
