Hydromorph withdrawal

I have been suffering for the last 8 months with sciatica due to a bulging disk L5. I am also a recovering alcoholic 19 years. I try getting help from Physiotherapy, Chiropratic who also had one of those tables that stretched you out (can't think of the name right now sorry) and Acupuncture. None of this helped it only made it worse. The thought of putting dilaudid and hydromorph into my body was horrifying. Having said that my back pain was so severe it was all I could do to get up and use the bathroom so I didn't wet myself in bed. I lost 28 Lbs in 3 months before I started to feel any relief. My Dr. had me on 4 mgs X 4 per day Dilaudid and 24 mgs x 2 per day Hydromorph. I finally was accepted into the pain management clinic here and was given an epidural shot to block the nerve while I await an MRI (waiting list for 7 months). This shot has allowed me the chance to wean off. It took me 40 days to wean off the dilaudid 2 mgs drop every 5 days. Not too many side effect. A lot of emotional stuff though, crying for hours on end. Once off the Dilaudid I waited for 2weeks before I started to wean down on the Hydromorph. First drop was in the evening pill went from 24 to 18 with few or any problems. Had no problems until now I have just dropped on my evening pill 18 to 12 (still taking an 18 in the morning). I have felt like crap for 4 days and I am due to drop my morning pill tomorrow Nov 19/13. A little bit nervous about this. Has anyone else been through this and what advice can you give me. I must say just writing this out feels good, kinda like an AA meeting.
