yeah, the whole "don't hold it in - hold it in" thing tickles me a bit, as everyone sais, and doctors say, it doesn't get you higher, but, as other people say, they feel higher, then as other people say, it's oxygen deprivation, well if thath's the case, i wouldn't mind suffocating one bit, as that apparent deprivation, i could fly to the moon on that feeling when i'm holding it in, as opposed to just blowin it out.
as to coughing, never, only time i will cough is if you get me to run a mile at full speed then start hitting the strong stuff
