Hey first of all good job on the 48h! I stopped smoking 4 years ago. I quit cold turkey. I remember thinking life would never be fun again without the smoke. This feeling lasted for about 12 weeks. It's tough you need to hold on. After it gets easier but the craving will be there for at least 6 months.

The good thing is that now, 4 years later, I never think about smoking at all. I don't miss it ever and I consider it one of the better things I have done for myself. Keep it up it's worth it in the end!
