Ed, you body is going thru detox. You are going to get worse before you get better. All I can suggest is Gatorade, V8 juice, some ice cream for the heaves. Lots of liquids, you have to get that evil liquid out of your system.
I needed Zanax, but you need to get to your Dr. for that. And be warned, it's as addictive as alcohol. I'm sending you a PM.
