Opiates, when properly used, are used for pain, and pain only. Misuse leads to addiction. There are treatments for anxiety, and they are not opiates. See your doctor about your addiction problem and your anxiety. Also keep in mind that your anxiety may not be emotionally based. There are physical ailments that can cause anxiety. Be sure to ask your doctor about this.
Also there is a substance abuse forum on med help! I would copy and paste this to it. The people on there are awesome
Welcome to the forum! Yes to all of your questions. Opiates can do all of those things. Those flu like symptoms you are experiencing are the beginning of withdrawals. If you decide to quit, which I hope you do, the pain will get worse for a short period. The upside though is it does get better! If you have anxiety I would definitely see a dr about it. Opiates are great for everything at first. Then like most of us they end up messing your life up and causing more anxiety than you had to begin with! The sooner you get off those little devils the better! You can do it! More people will be along soon I hope!
