Sounds like it could be withdrawal—I’ve had similar reactions coming off benzos. I am not a doctor so I really can’t say for sure. I know—that does not help much. Most of my symptoms passed in a week or so.

I am glad you have decided to get clean. This is a good step in the right direction. Keep us posted on how you feel and your thoughts (if you want). I’ll be here most of the weekend, so PM me if you feel an urge to use or just want to talk. Sometimes it helps to talk to another person.
