Ok I uped it to 286 mg. I'm startin to feel a little dizzie and am feelin just a little drunk. I had to take some stuff with acinominophen in it and psheudo because I am out of vicks44 which had nothin but dxm in it. So I need a question answered QUICK about acinompinophen because the rest that I got left has acinominophen in it. How much acinominophen can I take safely in mg's without haveing probs? I'm at 286 mg now and need to up it to 310 mg of dex. PLZ ANSWER THIS.
