Totally relatable. For me it was M.D.D. and Mixed Apnea episodes together each disorder compounding the effects of the other. I could sleep for 16 hours and wake up tired. Needed naps all the time. Sometimes falling asleep while driving. Had trouble focusing and remembering enough at work that I lost my job as a developer. Too tired to check my messages, answer calls, or do anything I used to do for fun. Took every pill, powder and potion I could get my hands on over the counter. But I seemed fine. Still on the tail end of that episode.
