I have to use 2-3 alarms if I am traveling or if my husband is traveling. If he's home, he will nudge me out of bed. Inevitably, I occasionally forget to turn one off and wake up pissed off at 5:15 on a Saturday! Yeeeow, that makes me a grumpy beyotch!
I just get frustraited because I have a lot of stuff on my mind and by the time I go to sleep its like 5 AM and then the alarm doesnt go off. *Grumble* Talk about annoying!
