Welcome to KTC. Lots of military around here, so any special issues are covered.
Head over to the April 2016 quit group, say hello, and post roll. Roll is your promise not to use nicotine for 24 hours. We post roll every morning when we wake up.
Bear in mind nicotine is an addiction, not a habit. (Know your enemy). Quit is simple, but very hard to do. Drink lots of water, exercise, read this site for inspiration.
Being surrounded by dippers will not help, but plenty of quitters win in that situation anyway.
