For me it was only two days. The third was easier and today is my fourth day and I feel like a million bucks again. Still think about the pills all the time, but not craving them as bad today.
I also have Ambien to help me sleep at night and it has worked like a charm.
Hang in there.
Just keep going on the same path. The withdrawal period takes different lengths for different people. the meds you got should help a little but remember that the first 4 days to a week are the worst so just keep trying as hard as you can and you will get through it. DONT RELAPSE!!! Just keep thinking positive, go exercise, take a hot bath, play some games, go to a movie, go on vacation even...anything to take your mind off of your current situation. It's going to take time and its going to hurt a little but you have to suffer a little in order to get healthy again...Keep on the path towards sobriety!
We all have faith in you and we know you can do it!!
