| I know that for me, I am able to taste the difference usually. Regular coke seems to taste a little thicker than diet coke, if that makes sense. I know that usually, when I am in doubt, I have tested the coke on my meter. If it comes back as HI, then don't drink it. I am not sure how recommended it is to do that, but I know that it has been the lifesaver for me before. Just don't do it too often though because test strips aren't cheap...lol
