So uhh i'm a student on weekdays i sleep at like 12-12:30am and wake up at 7am, so I'm getting around 6-6 and a half hours of sleep. On weekdays, my body feels physically slow and low of energy and when i try to play osu streaming is difficult and my fingers feel heavy. On weekends, I feel like I have a lot of energy (I get 8-9 hours of sleep on weekends) and when i go to play osu everything just feels right. Now, could the issue here really be just lack of 1-2 hours of sleep? Does really only 1-2 hours of sleep affect my performance that much? Please someone answer me.
