If you can make it thru 5 days without a fag then you can make it thru 50, 500, 5000...
I mean, you're literally doing the HARDEST part of quitting over and over and over again. The first few days are by far the hardest. It only gets easier and easier the longer you go.
Put your big boy pants on Leon, suck it up, and stay off the damn fags. You CAN do it, IF you choose to do it. The choice is yours and yours alone. Nobody else can do it for you.
