I recently did a sleep test because i was really sleepy and tired during the say an my apple watch is telling me i have too many wake ups. My AHI score is 33 which is quite bad. I immediately got A CPAP (auto) and after a week of using my AHI is now 1.3. And my brain has become so clear and alert. I can't imagine how I lived before once i got the taste of normal brain.
