Maybe lsd has changed since the 90s but 2 or 3 hits lasts longer than 24hrs. I don’t see how “hundreds” would be survivable. You would probably just die of exhaustion, there’s no sleeping on lsd and the harder you try fight it the worse it gets.
If 2 or 3 hits was lasting longer than 24h, there's a good chance it was something other than LSD (like DOM) or you have an idiosyncratic reaction.
I've met a couple people who took 100+ hits at once and survived to tell the tale. One fellow took what what was around 1000. The psychological aftershocks took him months to process, but at the time we met he was normal (well as normal as you'd expect from a person brave enough to intentionally ingest that much) and healthy.
To overshare, 2 or 3 hits wouldn't even hit me hard enough to stop me from doing Anki or reading, except for the relatively short time I'd be peaking. I could definitely sleep on it after the peak (but wouldn't at current prices.)
