Welcome Biologyteacher and congrats on your 2 & 3/4 days, I'm sure it seems more like 2 & 3/4 months right now. I've only got about 3 weeks and it seems like forever. I have to remind myself sometimes that it took a long time to get my self this F'd up, it's probably going to take a little while for things to get better.
I had a good friend who got hooked on lortabs. It was really sad to see. I ended up moving from the area, but last I heard he was still hooked. I'm sure the physical stuff must be really tough. There's probably some folks on the Substance Abuse board who can give you some advice about getting through those.
About the only advice I can give you is to try to remember how you are feeling right now. When you have those urges to use, try to remember these feelings, how crappy you feel. You don't ever have to go through this again.
Keeping a good thought for you!! Feel free to post your daily progress, thoughts and feelings here. Take care.
