Hi, My Name Is Troy And I'm 20 Years Old.

Hi, my name is Troy and I'm 20 years old. Ever since a month and a half ago I've been getting very fatigue in the middle of every day. I haven't had any exercise lately because I'm in the process of getting a new car and can't drive to the gym. Anyway, it seems like every day from 4pm-6pm I get extremely fatigue and need to take a nap immediately. Also, whenever I get hit with this fatigue, I find myself running to the bathroom to defecate several times. This happened to me again earlier today at 3pm when I went into work. I went to the bathroom and stood there for a while to drain everything out. Then I ate Jolly Ranchers and drank ginger ale. After I started doing that I started to feel much better. Still a little weary but much more able to function. I recently got tested to see if anything is wrong with my thyroid and everything was fine. I've never had problems like this before. Please help.
