Only symptom is that I have been tired all the time since about that time - don't sleep,just tired and often close my eyes. I haven't had any tests - told my primary Dr. over the phone and she sent me prescrilption for Namenda. I have High B>P> under control, heart conditions ( CAD,PAD and something else). I just don't like always feeling tired. I rest but nnever go to sleep and lately have taken a sleeping pill at night.
