I would advise you to drink water. You need to drink nine to ten glasses of water daily. If you try to wake up a few days earlier, it may become a habit to get up earlier. However, it is normal to get more sleep if you work hard. Still, you have to try to get ahead of yourself. Six to seven hours of sleep is the best sleep for a person. If you try to get 8 hours of sleep instead of 9 hours of sleep the first day . Thus, after a few days, he took the target of 7 hours of sleep. You will succeed in this InshaAllah.
