I quit when i was 32. Chew 16 years, half my life. Decided one day it was enough, still had half a can left. I still keep it, although it's probably pretty dry now, it's been a year and a half. I'll have one or two when i'm drinking with the boys, but never have the cravings anymore during the week when i'm working. Believe me though, the first few months really sucked, especially sitting on a tractor all day. I could have kept a few loggers in business with all the toothpicks i chewed up. Glad i did it though, it's pretty nasty, expensive, and my family seems to like it.
