ac0918,
I have de-toxed myself twice from pain meds, and yes, it is 5 days of no fun, but you can do it. Depending on how much you have been using, and other drugs and/or alcohol you have consumed, withdrawals are not all that bad. Under a doctor's care is best, of course, but unlike benzos or alcohol the withdrawal is usually not life-threatening.
Keep posting, take a lot of hot showers, and I know it sounds impossible, but get some exercise if you can. Benedryl can help a bit with sleep, but I would be sure to have some good movies at hand in case you are up in the middle of the night.
It goes like this: you are probably experiencing withdrawal now, which will peak on day 3-4. After that you will feel a little better each day. There is a lot of sweating involved, plus chills so I slept under a comforter with a bath towel at hand to put under me. (The sweat makes the bed wet and then you get chilled). But if it is the middle of the night and you can sleep at all you will want to keep a towel handy.
Drink plenty of water!
You can do this. Withdrawal is overrated as a malady; really it is not worse than a bad flu. Do it this time and you will not have to do it again.
