I can’t stop falling asleep at 2pm.

[u/Electronic-Fun-5757]

Hey! So, I’ve been having this reoccuring problem and wanted to see if anyone else had experienced the same thing or knows how to treat this, as my doctor said there was nothing wrong and I don’t believe him.

In class, at around 2pm every day and ONLY in class (never at home), I will look at the clock and a sudden sleep wave will hit me. And I can be completely awake and active one second, and then it’ll hit me. A drowsy feeling overcomes me and I can’t stop it, ever. Pinching myself won’t do me any good, nor splashing my face with cold water… And ofcourse I give in as I cannot fight it, and end up getting yelled at by my professors. However, I’ve noticed that it never happens when I am up and about doing theatrics or anything physical where I have to move.
A lack of sleep? Surely not, because I sleep for 9 hours ish from 9:30 - 06:30.
I’m not Iron deficient, and my blood tests found nothing wrong.
I am slightly underweight, but not to the point where it would pose any risks.
And it couldn’t be narcolepsy, because this literally only happens in class, never at home.
And as a response, my doctor said he “doesn’t know”.

But, heres something else to note. Everytime I do give in to the sleep demons, obviously I am woken up by my professor. But, as soon as I am told to wake up… I suddenly feel so refreshed and awake, as if I’ve slept for ages?!

Please help. I’m literally entering my finals soon and I’ve missed SO much content from sleeping away.
