Sorry to read you are having a tough go of it. I weaned off of Effexor last summer and I was truly scared to death as I had heard so many bad stories. My Dr. did keep me on a low dose of Celexa and I noticed a brain shiver once in awhile but otherwise I did well.
I made sure I drank large quanties of Smart Water and took my fish oil capsules. Don't if it helped but I know I felt OK weaning off. I hope these sx burn out soon.
As far as benzos, I have 2 mg of Valium to use when necessary and my Dr. is very strict about how many she prescribes. IMHO this is a good thing.
Keep on believing in yourself and you will make it through.
Kindly,
Kitt
