So this is my third time being sick in about 2 months. First time I got sick it was just a cold that lasted a couple days, then about 2/3 weeks later I get the same thing. A couple nights ago my body started aching and I just thought it was because of this workout that I'm doing because it is pretty intense. So I go to sleep and keep waking up throughout the night and the next morning I have an extremely bad headache, my entire body aches, and I have a cough. My head isn't that warm and I don't have a stomach ache. But I can barely eat anything, food's not appetizing at all. For over a month I have been taking liquid vitamins, zinc, vitamin c, and apple cider vinegar. I don't know why I keep getting sick. I don't remember the last time I was this sick to this degree. I workout out daily. I just started this workout over a week ago where I go to the gym 6 days a week and it includes a lot of cardio, which I am not used to. Am I over working myself. Someone help me because I don't know what is wrong with me. I don't get sick that much so this is very frustrating.
