Yes, I set up an alarm before I sleep. I make sure that I have 3 sets of time that I set. I need to wake up before 7 in the morning everyday because I have work. Before going to bed, I set up 4 am, 5 am and 6 am, sometimes I put 6:30. I really don't know why I did this. The 4 am is for my mother. She needs to wake up before me because she will do something and she will cook breakfast for us. The 5 am is for my mind to be prepare that I will be waking up at 6. The 6 am is still to tell my brain that I should be waking up before 7 in the morning. It sounds annoying but this type of adjustments really work for me. Although it disturbs my sleeping and other people who are still sleeping, it prepares me to my final waking time. I cannot live without an alarm, although sometimes, my body clock is the one that his helping me to wake up. I just make sure I set the alarm, just to be sure I will wake up on time. This means also that I have to charge my mobile full before sleeping to make sure that the alarm will snooze on the right time.
