I don't have to use an alarm to get up in the mornings. I have a Rat Terrier that just like an alarm, wakes me up every morning of the World at 5:30 A.M.. When I was working that was my time, so he has continued, without fail, to take the place of the clock/radio. God, if I could only break him of the habit.
No alarm clock no wake up for me.
I use the alarm on my cell phone. It has 5 alarms and I use them all. I am a big snooze button presser, so what I will do, is I have to get up at 7, I set one for 6, 6:15, 6:30, 6:45, 7:00. This way I am guaranteed to get up by 7 lol.
Never have used an Alarm Clock. Always wake up on time by myself. In fact I do not use any clocks much at all. I do not own a watch and there are no actual clocks on my walls. There is one on the computer and the cable box and maybe the microwave but other then that nothing. I tell time more by the sky and it has served me well here. Guess if I was in a bigger fast paced city I might need clocks but I liked the relaxed atmosphere of our small town.
