My 91 year old mother becomes hysterical because she does not sleep through the night. We catch her napping, which she denies. Her physician prescribed her some anti anxiety medication to help her sleep, but she claims it does not work. She becomes so worked up that we feel helpless. She becomes belligerent when we tell her she is napping and that may be part of the reason why she doesn’t sleep. Does anyone else deal with this issue?
