I work full time in healthcare. I think it helps me focus better. I am 57 and have no health problems except controlled diabetic. I do take prozac and wellbutrin for depression. My shrink put me on the numenda. My primary care doctor doesn't think I should be taking it since I have not been tested. What do you think? I do feel better with it. Do you think even if I don't have dementia or ahlziemers , it should be taken?
