Welcome, nice job posting roll.
Like Palp said, we take it one day at a time here. Make your promise (by posting roll), and keep your promise. Do the same thing tomorrow, and every tomorrow afterward, and you won't fail. Simple as can be. Hard as hell, but simple.
What is life like without nicotine? Much better than with. At least after the fog has lifted. When will the fog lift? It's different for everyone, and it's a gradual process. But you are likely near the end. But still be ready for ups and downs. Even after 100 days quit, you'll get what I call "come out of nowhere and smack you between the eyes" craves. That's when your daily promise is so important.
Buy into the method here, and you will succeed. Get to know the guys in your group, exchange digits, read all your schedule will allow.
