I have noticed lately that I am truly exhausted, some days to the point I cannot keep my eyes open, I am not working any harder in fact I have slowed down a lot. I have pain in my arms and legs, muscles mostly, some cramping in my calves. I am extremely thirsty most of the time, sometimes do bad I get cotton mouth between gulps of water. I have never been a huge soda drinker, but I want soda more and more. I have trouble focusing on my work, as I am nearly dozing off at my desk. My eyesight is not the same, as if I cannot focus on things near to me. I feel out of my head at times and a tad confused. I have also noticed that my urine is very sticky, and sweet smelling at times. Most of the symptoms have been in the past few weeks, the fatigue and pain over the past few months to a year.
