I have been taking hydromorph contin for about 6 months now and I get about 80% pain relief from it. I also find that it starts to wear off after about 8 hours. Right now I am prescribed 18mg & 24mg plus an additional 6mg for pain attacks. I love that I can take it and still function i.e drive my car because it doesn't make me a zombie the way oxycontin did. Is hydromorph contin available in the U.S.?
