Oddman - you DID make it through day 1 and you ARE headed to better days. Alot of us have relapsed and come back and it IS a big deal. Right now it's a very big deal to me that I have 5 days. I know exactly what you mean about being irritable and tired. I'm still feeling some of that, but each day is better than the one before. I haven't gotten much done at all. I've eaten too much, slept too much (or not at all), avoided going out alot, let the dishes pile up, etc......but it was all necessary - anything goes this first week as long as I do not pick up that first drink.
Remember you're not alone!
