Hi Glenn ... I don't know if it's recommended or not. If you're drinking "really heavily," I'd be concerned. I quit drinking a couple decades ago when it got out of control, and I think now, "What would be the harm?" Then I think of me with my REALLY unsteady balance and five falls in the last month, and picture me with a belly full of booze and what it would do to my judgment as well as my balance.
I know a lot of PALS enjoy a few glasses (or puffs) of whatever, and they have no problems ... it adds a lot to the quality of life for those who can handle it. But if you're drinking heavily, that's a different matter. Heavy drinking does so much damage to the body and brain, it's kinda crazy to add it to the damage ALS does. One of the direct effects of heavy drinking is neurological damage very similar to the symptoms of BFS ... only it's not benign, as I believe the neurological damage from heavy drinking is permanent.
