I mentioned to my sleep Dr. that my short term memory seemed to be getting really bad. He suggested I try Aricept, a drug that is given to Alzheimers patients. He also said it might increase my REM sleep. I researched the drug and it didn't seem to have any really bad side effects so I have been using it at the 5 mg dose level for about a month. I still can't tell if it has improved my memory, but it has almost doubled my REM sleep. I am also starting to remember some of my dreams which I haven't done for years. I have a sense that I feel better when I wake up. Does anyone else have any experience with this drug?
