hi there,
couple of things,
what mood stabilizer do you take?
I take lamictal, it helps with depression and I take it at night too.I used to take ambien sleeping pill but became afraid of it so now I take slow magnesium, which helps relax your muscles.
I also take a small dose of geodon at night...even though I am not manic right now...my pdoc believes I should take this as sort of insurance...I am bipolar 1 so I tend to run high instead of low.
I wonder if you might find working at home a better option for you?
Have you arranged your own office and chair to your body requirements? like egonomics!
You could be a computer consultant....

I am very sorry that you are having continued back pain, issues.
Did you have an accident?
My neice now has a herniated disk from cheerleading....she is only 16.

I know that it is hard making new friends when we get older...even harder if you have limited abilities....Forums are a great place to meet new people.
I post at the sister forum neurotalk...I am bizi there as well.
I hope you sleep thru the night.
