Hello lol, That is not possible. You have to sleep an adequate number of hours every night to keep your body healthy and energetic. If the number of hours are not enough and that for a longer period of time, it will certainly effect your overall health, concentration ,energy level etc...Sleep is an essential requirement for your body. So sleep tight zzz ;)

The average person only needs about 8 hours of sleep. As long as you have 8 hours of sleep and 3 meals a day, you should have energy.

You can try to do Yoga and meditation,relax your brain.

You can do it, but it's gonna take real efforts, especially in the first days of change. If you feel tired, taking short naps during daytime is an excellent way to help you feel better. Source: Personal exp. I'm trying to stay awake as much as possible for my Japanese study.

One thing you can do unless you may sleep more efficiently . Taking a free exercise is a good method to enhance your physical fitness . You may have better sleeping quality and energetic in the daytime .
