I had bleeding ulcers that perforated in 2017 almost killing me. I was on 62mcg of Fentanyl and 50 mg of Vicodin. I came down to 60 mg of morphine within 4 months and within 2 years the ulcers were bleeding again badly and they removed my Vegas nerves, gall bladder, half of my stomach and reattached my bile duct to my small intestine in 2019
