What were you taking? How much?
I was taking 25 percs a day for years and quit cold turkey, the first 4 days were HELL, see if you can get some valium from your Dr, thats what helped me get through it, I only needed 3 valium in the first week, it helped with the anxiety and the pounding chest
How many days since last use? Go to GNC get a good multi vitamin and some B6
