Welcome Nick and thank you for your service. You'll find a lot of military and first responder types on these boards.
I don't think I need to tell a military guy why quitting with a band of brothers is more effective than quitting alone! So start exchanging digits to increase your accountability (accountability being the KTC special sauce). Chase people down who haven't posted. Text each other to offer encouragement. Post about what you are going through. Lean on everyone here - and let them lean on you.
Read all you can about addiction so you understand what nicotine did to you physically and psychologically. See it clinically. It helps to learn to HATE nicotine so you stop romanticizing it. Good resources to be found
HERE.
Proud to be quit with you today.
