God bless ya! You must be going through quite an ordeal right now for sure.
Trust us when we tell you that the longer you use these medications, the worse coming off of them will be. Having first hand experience with Dilaudid, I can tell you that long term use of this particular drug can have some serious W/D.
I will tell you that your doctor will take care of you when the time comes. As a matter of fact, from what you said, he already has.
NOW, with that said - you are using this for LEGITIMATE PAIN!!!!!! You should absolutely speak to your doctor about coming down. DO NOT let us scare you about using this for your pain right now.
I took this medication for months and months so my story is a it different.
