@Bill Ahhh, Someone important said, Good sleep is the foundation of good health. And how marvellous you're feeling the benefits! Definitely fair game to comment on something I've put out there - and I really appreciate your input. I have my husband's sleep study, and he somehow slept for 6 hours, getting full sleep cycles! I don't know how he did it. I only got an hour and a half, and they pronounced me fine on that basis! Well, I'm not bloody fine now. You've prompted me to discuss the machine again with him, so thank you. He doesn't think it's an issue because HE'S sleeping just fine with an antidepressant called mirtazapine that knocks him out cold. I don't know how likely it is that I have apnea - I sleep so quietly that when I'm napping in the day, he checks my pulse! I'm going to push hard to see a sleep doctor myself - I think I have Alpha Wave Intrusions waking me up. I should be in Delta Wave sleep, but BAM! woken up by sudden Alpha waves. Determined to join you in the Good Sleep Club!
