I've been drinking alot of diet cola, myself. That's probably the next bad habit to tackle (my daughter is always trying to get me to quit soda because it's so bad for me). One thing at a time. I'd like to get confident that I've gotten the beer habit handled, first.
I like your idea, unbroken chain, about checking with each other at the end of the month. It's always easier when you have someone else motivating you. See you on the 1st.
