Welcome to the family.
Whatever you do, don't drink. If you're feeling very badly do get medical attention. If you drink you'll just have to start all over. I relapsed a lot, too much, before I finally quit, and each time I quit again the withdrawals were worse. Don't put yourself thru that hell over and over. Quit once and be done with it. Physical w/d usually only lasts a few days to a week, after that some support is in order to stay sober. Lots of us here are staying sober using only this site. I see an addiction counselor once a week and she's very helpful.
I find SR to be wonderful support any time of the day or night.
We're all rooting for you to be successful, so post your thoughts and questions and we'll do our best to help you out.
