I didn't think anything was abnormal about this until a friend mentioned it to me... she said it might be a vitamin defficiency or something.

I notice that everytime after I eat or exercise all I want to do after is take a nap and sleep. And I've noticed that it happens everytime. What is wrong with me? Like today I went to the mall for a couple of hours, got home and slept for two and a half hours. I just woke up. And it's not like I'm not sleeping enough during the night. I usually sleep in for like 10-12hrs

I've also been having this weird cough that doesn't go away. It's not flemmy or anything. It's dry and weak and it kinda sounds like a smoker's cough but I don't smoke. It's on and off constantly and this one's been happening for months now. I don't have a cold or anything. My friends and family said that it isn't normal.
