Don: Thank you very much for the info. I read the description of sleep apnea. There are several symptoms of sleep apnea I do not seem to have: daytime drowsyness I weigh about 145 lbs - can afford to lose another 10 lbs. My blood pressure is close to the upper limit: 140/78/73 I do not have vriable pulse rate. But, I do snore. I guess I should see a specialist and get to the bottom of this. Thanks a lot.
