First, I saw your other post which was more detailed.
Again, as a suggestion post on the addiction forum and you will get much support.
Me, I went through the "normal" w/d physical symptoms- rsl, insomnia, diarrhea for about 7 or 8 days. I still have sleep problems with anxiety and some leg cramps- my dr. gave me xanax which i take only at night, when i really need it to sleep. it helps me. But i am an addict and don't want to take too much.
I am 57 years old. I have had some nasty dreams in my life, related to my tour in Vietnam. But not necessarily from coming off the vikes.
It will get better. For better and more info post the other forum.
How long before you started sleeping Correctly?
Post your question on the addiction forum.
There are many persons with valuable information.
They helped me. i have been off vicodin for 28 days.
Good luck
