I am an adult male in my 30's. Almost every morning when I wake up I feel tired and just want to stay in bed even though I got a good nights sleep. about a half hour after I wake up I start to feel more awake. I also feel tired some times in the middle of my work day. Is it normal for an adult to feel this way ? Do you ever feel tired when you wake up and in the middle of your work day ? If you have this problem how do you deal with it ?
