So I am 18 years old and have really terrible sleep problems, and since I am actually up in the morning today (HALLELUJAH) I thought today would be a good day to start getting back on track. I don t work at the moment, so I don t have to bend around or anything. So what is the actual scientifically proven given number of hours that is beneficial for an 18 year old female? And what would be a good bedtime to give myself? And what time should I set my alarm to wake me up?
