I know precisely what you're describing, Biscotaki. In one of your previous posts, you mentioned it felt like having a stroke, total weakness of the body along with other symptoms. It's your body trying to adjust to new conditions (functioning without drugs). Part of this experience might have been also fuelled/or it then caused panic attack/s, which in itself are a WD-symptom. It feels terrible, but it always passes. Very many people who suffered from WD experienced it too. Hang in there!
