For Alzheimer's Disease "My poor mom was up all night with bad nightmares and talking all night in a state of confusion. Today she is like a zombie with no appetite and refuses to get out of bed because she is so tired. I should have looked up the side effects first. I am livid with the doctor that prescribed this."

For Alzheimer's Disease "My first experience with donepezil 10 mg was nasty. It affected my sleep in a bad way and made my memory, speech, and basic cognitive functions worse, and I was continuously lethargic. After 2 months on the drug, I can honestly say I feel a huge difference (for the better). There is a big improvement in both my memory and speech, and it's really made a difference in my day-to-day life and daily tasks."

For Alzheimer's Disease "Been taking donepezil for a little over 2 years. Began on a very low dose, had zero side effects. Currently taking the max dose, stools are rather soft but not watery. Often feel very tired, however, I force myself to walk and do light exercise. I have tried to enter Alzheimer's studies but pass all cognitive tests with high scores and have not been accepted in any study. Assume medication is helping or I was misdiagnosed."
