Day 3 is the worst, so hang in there. Once you make it through the week, be prepared to feel a little mentally out of it. It's normal to be depressed and have cravings, and this is where you will need your willpower. The depression is unresponsive to a lot of antidepressants for some people, though wellbutrin seems to work.

Are you getting off it for good, or just taking a med holiday? If you are trying to get off it for good, just keep in mind that the depression/boredom is cauesd by the opiates and is not what you are really feeling. Lomotil, a diarrhea med, actually has a demerol analog in it, and is great for w/d, you can really knock out some of the physical w/d symptoms. If you go to a doctor and tell them you've had excessive diarrhea for 2 weeks, you can ask for it by name and get it- i believe it's a schedule IV, but it barely crossed the blood brain barrier, so it works great for diarrhea and the physical side of things. I'd highly recommend it. You might also want something for insomnia, whether a short run of ambien or some kinda benzo to keep your head relatively straight and to help you sleep.

Good luck, and make sure to congratulate yourself when you finally get through it.
