hey mia, yes they knew and im only taking for pain mngt not feeling a thing but it does help w pain. Im better today and prob wont need them much longer. Im sooooo proud of u and yes I think addiction is always gonna b a daily battle. soo glad u are doin sooo well it gives me much needed hope! They gave me shots of Fetnoyl and morphine after surgery but they did not help at all i was hurting. It took hours of pain and lots of tabs before the pain and discomfort subsided. Ive really screwed up my feel good receptors!!!! Just want to b normal again!!!!
