So... I'm not sure if this is a pattern right now for you or not, but I found myself increasing my caffeine intake after quitting alcohol. My poison was coffee. Went from one cup a day to a pot a day in 4 months. I get anxious in the morning after drinking alcohol, so I usually drink only one cup.
I treated my caffeine addiction the same way I quit smoking. I weaned off of it. 10 cups a day, the next day 9 cups... I don't drink caffeinated sodas when I go through detox. The caffeine crash combined with the sugar trip was too much. I use Reed's ginger ale or Hansen's soda. I'll still get sugar hangovers though.
