I just started working out again after about 3 months off and the first couple of days where fine but then i went 3 days ago and had to stop working out after my 3rd excercise because i felt like throwing up and probably would have if i kept going. I thought maybe i over exerted myself but then yesterday the same thing but worse. Could this be just because i havent worked out in a while and all the greasy food is messin with me? and if it happens to you do you just work threw it or stop?
