I ve been feeling sick for the past few weeks now. I have stomach aches, rarely painful but mainly naesua. Although I have not thrown up. Sometime eatting is hard because I get such a bad stomach ache so I don t eat. Somedays I have water and gum because thats all I can handle. I ve also been very, very tired no matter how much sleep I ve been getting. And almost everynight I am waking up and can t sleep the entire night through. I have been having mild headaches off and on. My muscles sometimes feel weak and sore. Even when I haven t been to the gym in a few days.
