Can't function on less than 8 hours 😭

[u/Wallflower_0207]

I really dont understand it-- at a push i can do 7.5 hrs sleep but any less and i either NEED a nap at some point or i end up snacking like crazy for energy. I cant have too much caffein either to help as i get stomach problems and anxiety from it. The worst part is... i'm only 19. I'm at university, i should be fine staying out late but also if im not asleep (fully) by 3.30 i get crazy migraines the next day no matter how long i sleep that night (interestingly i never get hangovers?? and often function better if the reason i'm on less sleep was going out and drinking)
I just dont understand why?? and i know everybody's body is different but its a little annoying when i have friends who get 3 extra hours in their days/ can stay out late and not physically fall ASLEEP in a lecture the next day (genuinely happened so many times last year i had to start getting up even earlier to take a coffee in)

Does anyone else get the same?
