Caszee,
I too drank wine at home in the evenings and could finish a bottle on my own. I tried to moderate drinking in the summer of 2011, but gradually resumed drinking every day. My daughter had two operations in a year, and I stayed with her both times, and would feel guilty when I'd find myself thinking of wine.
I quit all alcohol, but wine was my thing, last June. The first week was tough, but I found quitting to be easier than moderating and I feel so much better.
I work in a pre-school, so am particularly touched my your young son's plight. Keep posting
