I drank a lot of "energy drinks" - e.g., Amp, Crunk, Monster, etc. for the 1st few weeks when I quit my every-other-day binges about a year ago. Those high-sugar/caffeine drinks gave me a beer substitute, especially in situations where I was used to having a beer in my hand.
I don't really drink those much any more, because I have gotten used to not drinking beer all the time.
Good luck with quitting, and welcome to SR. This is a great place with great people.
