Since you've been taking hydro for pain for a few months. It's stronger then davarocet (which is a synthetic opiate). So you've build a cross-tolerance to davorcet or any other narcotic which is as strong as hydro or weaker then hydro. So the Davorcet will do nothing for you, the enzymes needed to break it down already exist in the liver due to the hydro, so when you take the Davorcet, most of it is metabolized before it even reaches the brain, at best you'll catch a slight buzz with little pain-relieving activity. Davorcet only works on those people, who don't take opiates on a regular basis, their livers aren't hype-up on natural opiates, so they received more of a pain-relieving effect. Anyway Davron is a little stronger then Davorcet, but in either case they won't help you with pain. You have to take step-up, Percocet ES 10mg/325mg.
