Space cake
Depending on how much you ate, the effects can be delayed up to 2 hours. And if the coffee shop lady says one slice is enough for two, she means it.
I found out the hard way that two slices of strong space cake at about 21:00 and 22:00 respectively woke me up at 00:23, and started its peak at 00:37. At 1:10 it got boring and at 1:26 i was cleaning up puke. (I guess it doesn't suppress nausea while high with a full stomach.) Followed by 20+ minutes of worried dreams.
All in all, start early on the day with a small dose and wait 2 hours for an effect before eating the rest. It was more cerebral than mushrooms and about as strong as the 12 gram pack of fresh Hawaiian shrooms.
