I have a board exam coming up in a few months and I am starting to prep for it. The other day, I had gastric issues (vomiting and mild diarrhea) that I associated with my hyperacidity. I took care of it with meds and rehydration  Then, later that day, I felt feverish although my temp was normal. I thought it was because it is super hot (around 90sF). 

But I woke up and I could feel my heartbeat like palpitations. And I felt sleepy/dizzy although I have been sleeping a lot the past few days. My whole body just feels weird and weak.
