I have had flu symptoms going on 3 weeks. Started with waves of fatigue,nausea, headache, soar throat on a lighter level (I continued work and exercise) 2nd week fatigue increased a bit (went to work, no exercise) starting 3rd week went to doctor as it seemed worse and the next day everything was way worse. Was in bed last 3 days down out of work all week and Thurs. fog lifted and I got to 95% feeling like I could go to work. Went to be and woke up dehydrated because i had not been drinking water and felt like I went back to square one. I hydrated all morning gatorade and lots of water (my urine is clear). I am down again with constant nausea, foggy, feels like equilibrium is off and cold hands. It has been such a strange virus if that is what it is
