Yes, had a friend/roommate for a bit that had it, played for a band I ran sound for. Had been a decent smalltown journalist, but the disease really fucked him up during media downsizing. Lost his insurance/treatment and really cost him. Super hyper chainsmoker and paranoid when off meds, but only one that I ever met that could do all the Rory Gallagher licks without much effort. Didn't really drink or drug anymore but 1 and a half beers and he would start explaining how simple Hendrix and Clapton were, did their riffs doubletime.
