For Alzheimer's Disease "After my initial diagnosis, my neurologist put me on this drug. We have had to reduce the dosage twice. I’m down to 2.5 milligrams and still feel tired and in a fog on and off. I have had a few days where I felt pretty good like I used to, but I only remember one or two nights that I slept through the night since I’ve been on this drug, which is not very long. Several weeks. Now multiple bowel movements a day. I feel drugged."
