I'm not sure whether it's comparable, but Chris Squire from Yes spent months "hibernating" in a hotel after a bad trip with homemade acid:
“I’d had lots of good acid trips prior to that. But I made the mistake of trying some acid some friends of mine had homemade. That knocked me back, and I did sort of hibernate in an apartment in Kensington and spent quite a few months — maybe as much as a year — just playing bass.”

Ah, thanks. I didn't know the story.

Bad acid trips won't lead someone to change their life that drastically. (or so I've heard, not that I would know anything about that sort of thing).
