A lot of your symptoms sound like mine as well. I don't know what you currently take for supplements, but Andrew Cutler gives lots of good suggestions in his book for what to take for certain symptoms/problems to help you feel better while you go through detoxification. If you have achiness, muscle, joints, etc. magnesium is very helpful. I take a highly absorbable form called "Natural Calm". It is a powder that you mix with water and drink. I think you'd find it helpful for starters. I personally take Klonopin for my severe anxiety problem which I find very helpful and it is not very addictive.
Keep plugging away and get all the support you need.
