i have been on and off this stuff for 3 yrs. I have problems with my lower legs and feet from my diabeties. It works good most of the time. First i must say i have a little bit of a tempper but some times i blow up at my wife really bad over nothing at all, mostly in the am. If any one has had this happen please email me. i feel realy bad when i do the to my wife. the meds are what my wife and i can ony figure out.
