I was trying to make a decision just like yours on Tuesday of last week. I kept reading post after post here, then posted, and then made the decision. I'm now on day 7 and I'm here browsing, reading, thinking, and getting involved -- getting involved in something worthwhile.
Your fears about your health sound a lot like mine.
Good luck making your decision and hope to see you back here with a few then more days under your belt!
BTW -- Good for you, not turning around and rushing into the liquor store before it closed! That's a GREAT first step!!!!
