DEAR DR. ROACH: Since I can remember, I've always had the exact same sleep habits. I go to bed between 10:00 p.m. and 10:30 p.m., and wake up at 6:00 in the morning. It's been the same all through my adult life, until about one year ago. I'm 76 and have had high blood pressure since my 30s, a family inheritance.
For the past year, I have woken up at 2:00 a.m., go back to sleep, wake up at 4:00. The I go back to sleep and wake up around 6:00. It's like this seven days a week. I miss the continuous eight hours of sleep I used to get. I feel tired occasionally.
