Like Robert said, you are going thru withdrawal. Everyone is different. I started my "quit" cold turkey last Monday and it lasted 28 hrs before I was about ready to jump out of my skin with the restless crazy leg thing!
I had 8 hydro's stashed, and took them to keep from going ape sh.t!
I went to my PCP the next day, spilled my guts to her, and she put me on a taper program, since its obvious that I can't W/D cold turkey. In four days I've gone from 16 10/500 hydro to 7 10/500 hydro with the help of 2 #10
valium for the crazy leg and anxiety thing, and 2 350 mg
soma for sleep at night. The initial taper from 16 to 8 was pretty drastic, but It had to be done. I don't think I could have gone from 16 to 15 to 14 to 13, if you know what I mean. Maybe you can ask your Doctor to put you on a slow taper. I am a 50 year old man who has worked construction all his life. I consider myself to be a pretty tough guy.I stay in shape, I run 20 miles a week, but this hydro withdrawal brought me to my knees. My goal is to drop 1/2 a pill each day or so, until I hit zero. Maybe this is an option for you. If it doesn't work for me, then I will have to go some kind of
suboxone treatment, because I am not ashamed to admit that W/D is hell, & I just can't do it.

Good luck to you, and I wish you well.
