Quitting smoking.
Keep it up Jack!
I stopped smoking once for 7 years, thought i had it beat.
All i can say is after you stop, go through all of the crap to stay stopped, and NEVER in your whole life have one more puff......ever again!
I puffed on a cigar when a friend of mine had his first boy, he went around handing out cigars. Well i had a couple of puffs, was disgusted by the taste and smell, but i started smoking again within a month.
Smoking is the biggest head trip that i can think of.
When i stop again, i will never have even a puff ever!
Yeah, the sunflower seeds helped me a lot too when i stopped the first time.
