^^ This is one reason i choose to only do LSD early in the day now and in good physical shape. If it can't happen before 2pm I bail. I am a couple few years shy of 50 now so even without drugs sleep deprivation wrecks my life. IF I happen to have someone to to tend to life while I rest on a morning after I can trip a little later. Last time I had a late late MDMA session was because Mark Farina played a party and knowing that his sets are transcendent I dropped a roll at midnight, his set started at 1am and I left at 430am while he was still on after dancing non-stop. The kids got up at 7am and in spite of my wife's promise to let me sleep she said "welcome back to reality" and I got up to make everyone breakfast. Cruelty! :shock:

That one took a week to bounce fully back for this old(ish) head.

But yeah when I used to stay up for days on end I would see things and hear things, dream paralysis when i would finally rest. That was terrifying.
