I have noticed in the last several weeks I will suddenly become sleepy and fall asleep. sometimes I will be home and go to bed at any hour of the day but sometimes I fall asleep on the floor or in the car (not while driving) or just about any where. It's like I suddenly feel like I need to sleep and bam I'm sleeping. It's starting to bother me. Sometimes I am in the middle of something and next thing I know I am asleep. Sometimes it is only for a few minutes but other times it for an hour or so. I have started to keep track of it to see if there is a connection with when and why it happens. It's weird.
