I went on suboxone for cravings for oxycodone, I wasn't dependent. It helped for a bit, I stayed on lower doses because I didn't like the constipation and then the gastris followed. Skip 2 years later (now) I'm having troubles with hydromorphone. I am now back on the Zantac and my gastris is getting better, (peppermint and chamile tea; lots) so what I would like to know is what dose of Suboxone will fully block Hydromorphone? Since my stomach can probably handle it a bit better. Any details I forget I'll edit in later. Please help. I have to wait till next week to go back to my clinic. Thank you very much. Any help at all would be greatly appreciated. I have a hard time going to programs. Social Anxiety. Besides Segue for my Suboxone.
