I am currently on a trial of Namenda. After the first week, I believe I have improved. I completed several tasks today that I have promised my wife I would do for months. It is really hard to get goings most days. My problem is after the trial, my cost for Namenda is $357 a month. Is there an alternate for Namenda? So far I like the way I feel, but the high cost will force me to discontinue Namenda.
