I've not took them after acid as I've only done acid twice like a billion years ago, and had bad trips, I've took them after mushroom chocolate to go to sleep before the trip turned bad as I was worried I'd have a bad time so ended it by taking zopiclone
You trip on them if you try and stay awake, I'd suggest taking 1 or 2 then laying down to go to sleep,dont try and stay awake on them, they have a 20 minute window, if you go past that you can stay awake on them and then feel trippy, if you want to use them to sleep you need to take them, lay down close eyes and try and sleep then before you know it you don't even remember going to sleep at all
