I've experienced difficult menses since my teenage years. One of the more frustrating symptoms was feeling so sleepy for 2-3 days around the start of my period. Since I wasn't diagnosed with Narcolepsy Type I until my early 40's, there was no reason to suspect any connections. I had a hysterectomy this past February, leaving ovaries intact, and recently realized I'm still having 2-3 days of extreme sleepiness, as well as some of the other monthly symptoms. The big difference is that throughout the years of hormonal changes, the one symptom that worsened was the sleepiness. It's no joke to sleep 3 days in a row, only waking up to urinate once a day, maybe sip some water, and back to sleep. Has anyone else experienced something similar to this? Is this "normal" with narcolepsy?
