2 to 3 days for the physical stuff. after that, it is all in your head.
I haven't made it past a week for a long while now.
You really have to WANT to quit...
Biking helps.
I've been slacking like mad on the commute recently and smoking doesn't help.
keep it up. You really feel amazingly better after a while. It is worth it.
Just don't restart like me!! Then you just have to quit again.
you can do it!! (i need to too)
