I was just wondering, if it is normal to get drowsy spells during the day. I am a 20 year old male and I sometimes during the day I get spells and feel like I want to sleep. It makes it hard to pay attention some times especially during my college classes. I get plenty of sleep at night and sometimes it feels as if the more I sleep at night, the sleepier I am. Any suggestions??? I do take some medicine for anxiety, but its only taken when needed.
