I was on a trial run of Namenda several years ago... just as I was noticing that it was helping... I was taken off of it... I too was told the dosages allowed were far less than believe to be significantly effective for RSD.
I sure wish I could be a guinea pig for a higher dosage use of this....
Have nothing to lose and much to gain... if anyone ever hears of a trial going on let me know.
