What Causes Frequent Urination And Tiredness?

Hello! 2 weeks ago I had either food poisoning, or 24 hour bug. I was vomiting for 4 hours. I had no diahrrea. I drank Gatoraid to replenish eltrolytes. I was able only to have clear soup, tea, and Ginger Ale. Since then, I ve noticed that my energy has not fully returned. I notice that I get up 3 times in the night to go to the bathroom and feel tired when I wake up in the morning. I feel more like myself in the evening after having dinner. I eat 3 meals a day, no snacks, drink 8 glasses of water a day. I m on Sertraline, Estrogel, Progesterone, 0.05 Lorazapam, Wellbutron. I have no other health issues. What do you think is going on medically?
