First of all I want to say THANK YOU for everything you've done for us at home. You have paid a huge sacrifice and I respect you. My brother was 82nd and died a couple of years ago(not in combat). I'm sorry you're having this struggle. Quitting is difficult but not impossible. The best way is with medical supervision. Some people "taper" down dosage(I couldn't do it), some use maintenance drugs(Suboxone), some get medical help(medical detox/rehab), some quit cold turkey. Whatever you do make sure you get help from a doctor. Your body will "create pain" in order to get more of the drug. You have legit pain issues and probably chronic pain so it'll be tough. The opiates will make that pain worse by telling your brain to put more dope in your body. The addiction only gets worse so doing something today is important. There are a few options. Explore them and kick that 5hit. Good luck.
