I want to play Skyrim while I'll be tripping first time but I'm afraid of Creatures at night so I might just push T and set to wait for next day until it's bright so I wouldn't worry :)

i rate it was tolerance build up

Skyrim and dragon ball z is the sickest shit to watch/play while trippin'!!

If they had 5 g's in them, you'd def trip weekend after weekend for a while. The cookie was probably a low dosage. 

I actually experienced a similar unsatisfying trip once, when I waited too little time after my previous trip. So maybe it IS the tolerance, and you should maybe skip a week.
