Hi MerryRecluse,
Like everyone else said, just come back tomorrow, don't drink, and work out what you learned from this. Many of us have done the same thing.
My day was pretty darned sweet; I woke up at a ridiculous hour (4:30) due to a hungry dog and just stayed up. Had lots of energy, got lots of things done and still had plenty of time for some relaxation in the yard and pool with my delicious lemonade. What a change from getting up at the crack of noon with a hangover and barely being able to get my laundry finished.
I had a few moments of craving, but I did not let them consume me, and I did not obsess. In fact, I feel good about what I'm doing for my health. The cravings passed quickly.
It's now close to 8pm here and I'm starting to get tired, since I've been up for so long. Going to read the board here a bit and then see if I can get to sleep early tonight. If I'm lucky enough to be able to sleep. I never know these days.
