yeah ive blacked out before...but just from weed it was weird like i hit the bucket 5 times like in like a 10 to 15 mintue period and on my 6th they switched the bucket to a 3 liter and i got ready and hit it and jump up and down ...."that tends to increase my buzz " lol and then just went down in the middle of a jump and was laying there and just woke up like 10 min later lol
