Heyyy being tired all the time is a THING.. but you shouldn't 'just' accept it! I work in the overnights so i know what it's like to feel sleepy.. and its NO fun. It can be SO unhealthy ( especially for your metabolism.)
Here are 3 easy ways i try to avoid being tied:
1. Drink water... all the time
2. include veggies in almost all of my meals ( even spinach in a smoothie ocunts!)
3. I don;t look at my phone in bed while i am trying to fall asleep.
