Instead of caffeine, maybe try low doses of kratom. I hear it lasts longer, no jitters, and there's no withdrawal. Apparently 3g doses of niacin (***NOT*** niacinamide), every night before bed, will do fun things to your body that will re-balance your brain chemistry and make you more content being sober. People that quit drinking for *years* but never felt better, apparently do so once they do the niacin thing. Hell, I did it and can attest that the cravings almost completely went away. I still drink regularly, but try to make sure I always replenish B/K/C vitamins, and also take Maca root extract/korean red ginseng/fish oil pills daily. What can I say? I feel generally about the same, but these days tend to have more good days than bad days (mental clarity, fatigue, etc). Which, hey: I'll take it. Better than what it was before.
