After I got sober, caffeine and I had to part ways.
I'd say in hindsight, it was a contributor to my first slip. (I was finding the "down" from coffee was giving me hangover-like symptoms - and hey, we know what cures a hangover, right?)
Personally, this is what I had to do. Everyone is different. I just found everytime I reintroduced it, it would bring out alcohol cravings or dire mood swings that of course would star the AV chatting away. Made sense for me to cut anything addictive or mood altering.
