Quit last Thursday, had a bad 4 days or so. Right now feel fairly good except NO energy. I can barely walk to the bathroom and forget standing up in the shower. What is this? I have to go back to work in three days. I'm eating, I'm taking all my vitamins in the Thomas Recipe, and drinking water. Taking valium only at night. I'm about to give up.. It's a terrible strain just sitting upright in this chair. Please help!
