"suffering with chronic pain from debilitating spinal injuries, i was always prescribed acetaminophen containing hydrocodone. i was always getting bad acid reflux and digestive problems i would explain this to my original pain management dr. and he would switch me from vicodin to percocet and the constant stomach issues continued. i switched to a new pain dr. i told him i was feeling fatigue and constant acid reflux when taking my pain medicines. he suggested trying a time released pain medicine with no acetaminophen he felt i was taking too much acetaminophen and perhaps too many pills period (4 pills a day) he suggested to try zohydro, i am forever grateful i switched. great relief of back pain and stomach problems. 10 stars."
