I've read that another thing that helps with OCD is boosting the serotonin system. This can be quite effectively with high dose inositol powder, if you don't want to go down the pharmaceutical route (inositol is a vitamin). I use high dose inositol myself quite a bit, in my case to help counter depression. Dose levels are around 2 heaped teaspoons of the powder. More info on inositol for OCD here.
Combining a serotonergic boosting agent like high dose inositol with anti-anxiety supplements like NAG will presumably be more effective that either on their own.
As I mentioned earlier in the thread I'm leary of messing with her Serotonin because she is MAO A +/+. The mutli I'm giving her I mentioned has choline and inositol in it but it's a very small dose for each. Not sure if that's what is helping her from the multi.
I read very low dose amisulpride may be beneficial for ME/CFS, and it was one of the things that I randomly just tried out. I find it excellent, and still take 12.5 mg daily. It helps a lot with the sound sensitivity problem of ME/CFS, and I also find it reduces the irritability mental state that is common in ME/CFS, plus it boosts energy. So I think this is a great drug for ME/CFS. These drugs can trigger diabetes as a side effect, but I think because I am taking such a low dose (1/100 th of the normal dose), this risk will be much smaller.
That interests me, I might persue giving that a try.
