not HB woddrose.....but ive done morning glory which contain the same chemical....the only real difference is you have to eat like 5 HBW to trip but you have to eat at least 120 morning glory to trip.

with me they took fucking hours to kick in properly....i took them before going to a party...felt funny....left the party about 3 hours later and then they kicked in....i went back to my mates and put fear and loathing on.... things had the strangest trails....peoples faces were pixelated but just their faces and there were about 5 big pixels per face.....then i lay with my eyes closed untill i fell asleep.

i would recomend you try them if your into tripping
