This usually happens after a day at work. The drive home is about 30-40mins long with traffic and I always drift off and my biggest fear is getting into an accident. I am very concerned about this now because today I drifted off and bumped into someone's truck. I woke up in the nick of time and said "oh Sh!t" and braked!! Thankfully, They let it go but my car does have a small scrape and crack in the bumper now :-( but it could have been worse. Are their any remedies I could do to stop this from happening?? My day usually consists of getting up at 6am, getting ready, eating small breakfeast, then leaving for work around 7:20am. It takes about 30mins to get to work. I get their usually about 7:50 or 8am. I start at 8:30am. I am a teacher so I am moving all day. Finally my day ends at 5:30pm. Sometimes I go over to my parents which is about 5mins away from work. Sometimes I catch a quick catnap and then I leave to head home at 630. I go to bed usually at 1130 or midnight.
