there is no try. there is do and there is not. dump the shit and quit NOW, not tomorrow, not after this can, NOW. Does it suck, fuck yes it sucks but its the best decision you can make.
go to the top welcome center, read everything you can, post roll - your promise to everyone in your quit group that you WILL NOT use nicotine today, come back tomorrow and do the same thing, and the day after that, and the day after that.....
