Congrats on fighting the fight. Many people die before they even make the effort. I went through withdrawl a few times from Ultram and it wasn't fun, I got these horrific brain-blink things I can't even describe. I doubt that withdrawl can hold a candle to OC withdrawl so I feel for you.
Don't worry about tomorrow or next week, just stay clean today. Just fight it for the rest of the day. It sounds like you're already past the halfway point, and I know you'd hate to do this all over again.
Hang in there, come back and post as much as you need to, let us know how you're doing. Sometimes things start to be a bit easier to handle when you can write them down and read them to yourself.
