Over the last three days i've been experiencing headaches and nausea throughout the day as well as fatigue. I thought it was because my AC went out but it gets cool in the evenings and at work im in AC all day now and its the same. I've also been trying to eat well and sleep longer and its not really helping. I just dont feel right. I wake up and feel this way then I feel better, then when lunch comes around I feel this way again and then at dinner. Its before i eat not after. Usually at night its doesnt go away though until I go to bed. Suggestions? I'm right before going to a doctor but they will be closed all weekend, what should I do?
