Night sweats, unreasonable fears, jitters, emotional roller-coasting... all of that can come with the package, Over. It's safest to get medical attention and/or go to an official detox facility. Are you going to meetings? You're going to need support and direction. A Big Book to read and some hot chocolate to drink might help, too. Come by the Steps Forum when you get a chance. Probably best to start at Step One... Wishing you the best, friend. Hang in there.
