[robfitz]

I tried a bit of everything, and I did it all at the same time, so it's hard to pin down causation. The only thing that had to happen was to shift my diet away from being primarily composed of alcohol, coffee, and tabasco. Apart from that, a high-end probiotic thing may well have helped, and a good chiro/nutritionist acted as a sort of accountability coach to keep me going.

Also, getting serious about reining in the drinking acted as an anchor habit that led to a bunch of other positive lifestyle changes. (I still probably drink far more than almost anyone would consider acceptable, but it's down to a level where my body appears able to keep up. So still a work in progress, I guess, but at least my energy is back up.)
