Yup, bio major student with premed emphasis here. I balance them out by separating them geographically, keep yaoi/manga at home and keep school and life outside of home. Since I know I’ll just read yaoi endlessly at home, I make sure to stay outside during the day by making plans to go to the library, hang out with friends, or just go to Starbucks. Then at like midnight, I read yaoi. Sacrificing sleep is sometimes inevitable. Hope that helps.
personally, i keep my reading time as something i do before bed when i cant sleep (bl as my bedtime stories lol), or when i have a break. if schoolwork gets busy and i get notifs about mangas updating, i let them pile up. once i finish all my schoolwork, i binge read/watch shit as a reward for myself (=・ω・=) ngl though, its super tempting (i have to keep my phone away from me sometimes aaa)
i have a friend who binges when shes free too, and my cousins sometimes do marathons after midterms are over lol
I tend to read it at night once I get home after work classes and I've done my chores/homework. Of course, it doesn't always work out that way, but it's been working fairly well--I keep it strictly in my room, so I make a point of staying in the main area with my roommate until later in the evening ;)

Is anyone here in university? How do you people balance life and still have time to read yaoi?
