I took phenergan the other night for nausea. I got very sleepy but couldn't sleep. My legs were very restless, seems like my whole body. I had to get up and down all night. I was so sleepy - but my legs and arms just totally moved all night. Could this have been a side effect from phenergan?

Here's information on phenergan - it's an antihistamine and can cause the side-effects you mentioned. Pls see your doctor and tell him/her about your side-effect experience as you seem to be particularly sensitive to this med.
