Suggest Remedy For Chills, Low Grade Fever, Hot Flashes And Fatigue

I have been extremely run down since before Thanksgiving - on and off chills and very low grade fever or no fever at all. When I go to sleep, I get what seems like hot flashes - but during the day I'm just exhausted and forcing myself to get out of bed. I am medicine averse - but I can't make it through the day upright without a 1/2 of an excedrin pill - been doing this for almost 3 months - feel addicted but pretty a half of an excedrin isn't terrible for me. I force myself to go workout some weeks but some weeks I just have to go back to bed several hours after I get the kids to school. I am 48 and take progesterone in evenings.
