i have a problem but i dont know how serious it is. I wake up every morning at 4:30 am to do my cardio for 45min b4 work. My problem is i go to bed at 10:30pm that only gives me 6 hrs of sleep. I know its optimal to have 8 hrs but i cant help it there is no way i can go to bed at 8:30pm thats just inhuman besides i wouldnt fall asleep anyway. What do you guys think.
