The objective is to get poison out of your body. Take a multi vitamin and electrolytes will help. Excersice to help sweat it out would be wonderful but light excersice. Withdrawl is different for everyone. With me, it takes a week or more but that's because it's not in my system ever so my body is full of strange toxins. Ugh, I can think about it still.
You are on your way to recovery. I just wanted to stop by and wish you happy healing.
