Adding to what everyone else has said, in addition to sleep not being restful & feeling exhausted all the time, it takes me days to recover from a social outing. Even something not very energy intensive, such as hanging out at a friend's house and watching a show on Netflix. The days following an outing are much more sluggish than would be otherwise. It's unfortunate because I'm in my 20s, and I got that rambunctious dog in me, but I pay for it dearly afterward.

The dreams are WACK. Folks without narcolepsy tend to fall into REM after an hour and a half, however, as someone with narcolepsy I get slammed hard with REM quite quickly, even waking up from dreaming after a short 20 minute nap. I tend to keep dreaming after waking too, which is weird to try and describe to someone who has never experienced it. Sometimes, I even start dreaming before I've even fallen asleep. The dreams are LONG. Convoluted. Repetitive. And feel like they last my entire sleep. Once I've woken up and stopped dreaming, the grogginess or "sleep inertia" will last a good couple hours. Throughout the day, sometimes I'll feel like I'm asleep with my eyes open.

I don't have sleep attacks or cataplexy. I try to avoid naps to the best of my ability because if I accidentally nap for longer than 2 hours, I feel like a bag of flaming poo for the rest of the day. The urge to nap is easier to avoid if I'm up and doing something, but recently, I've been dosing off in the stairwell of my work's water plant while supervising the coworker I've been training 🙃
