Dad goes to bed around 9 pm. Gets up around 9:30 for icecream. Back to bed at 10. Up again for a sandwich and Boost Protein drink. Then after that he's up and down all night worrying about sombody stealing his money, if my husband and I are in debt (we aren't ). He'll call people at 4 in the morning. By the time my husband and I wake up he's hyper. He will literally talk all day almost non-stop. Repeating the exact stories, asking the same questions over and over. He also will become ma nice a want to spend lots of money. I'm about to pull what little hair I have out. Any advice?
One thing that got my eye is your Dad drinking Boost Protein late at night... no wonder he can't sleep. I would find a substitute drink real quick.
After two weeks, check with your Dad's primary physician for other recommendations for sleep, if there still is an issue... sometimes something as simple as an antihistamine would work, like Benadryl or Chlor-Trimeton 4 hr, but only if the doctor says it is ok to use. Don't use them on a day after day basis, just to get your Dad started on a regular sleep pattern. Long term high dose usage could up the odds a bit for memory issues.
