First, congrats! What you are doing sounds like the best choice you've made in a while.
Some things to consider:
1. Get new friends...giving your best bud all your drugs is not going to keep you clean.
2. Air Force does not take to kindly to drug use, either past or present. You might want to consider the Army.
3. Welcome to the rest of your life. It's going to be tough. You're going to see all your buddies having the "Time of their lives" getting strung out on God knows what...
Stay off it, kick back and watch...It will all catch up to them in the end.
My brother is pretty big into drugs...He's always offering, and I tell him that even if I wanted to, my job does drug testing...He thinks it sucks, but I would rather do business with a co. that does it rather than hide their head in the sand...
Just a few things to think about.
Good luck, and we're always available with open ears.
EDIT: Life's pretty f'n cool without drugs...I see crazy stuff everyday, and it's both comforting and frightening to know that I am not hallucinating...
You don't need shrooms to smile.
