Yea, they were the worst withdrawals ever but that's to be expected when stopping cold turkey at a dose that high. Days 3-5 were hell, I was a little better by day 8 being able to sleep some by then, but I would say it took 2 weeks for the acute withdrawals to be over. I was away at college at the time and I remember it being the two weeks because they were my only weekends at college where I didn't go out or drink at all. I lost a ton of weight and barely left my room for those two weeks, so my grades plummeted.
