My Husband is a truck driver and he does a lot of driving at night. He has been struggling lately with dozing off at the wheel. Instead of increasing his caffeine intake or taking harmful supplements, he decided to get a Nap Alarm. It is a device that you wear on your ear. It measures your head movements and makes a beeping noise in your ear if you fall asleep. He tried it out the other night and it totally worked! I am so happy that he got it. I now feel much more at ease about him driving at night and won’t worry that he will get into an accident.
