is this for real?
Please tell me this isn't???
You probably won't be able to sleep until a good 12-15 hours after taking that amount of LSD, possibly longer. But everyone's different. Some people don't have much difficulty getting to sleep once they've come down from the trip, others find it near impossible to sleep until the cid has well and truly worn off (e.g. me).
If you need to sleep at all on Saturday night or Sunday morning, I would personally suggest that you choose a different day and take it earlier than 6pm.
I'm thinking of dropping 2 sugar cubes of acid at 6 pm tomorrow, any idea how long it will be until I'm able to sleep? Would it be a better idea to do it earlier on a different day? This will be my first experience with acid.
