So I just recently added protein supplement to my diet. Before this, I was basically living on pasta, vegetables, and chicken (I would get 30 grams of proteins a day). I just had a protein shake a little bit ago (23 grams protein) and I now feel like I might puke. I'm not sure if this is from the protein or not, but has this ever happened to anyone else? Edit: This is my first week on protein, and maybe I'm just sick becuase my head feels warm too.
