Is it ok to take apple cider vinegar and honey with mylanta?

Yeah it is... though it's a bit counter productive.

You're drinking an acid (vinegar) with an antacid (Mylanta).

Sort of cancels out the two.

You'll be a bit gaseous... well more than a bit.

Just mix the two and watch the mess. Or drink the Mylanta and then drink the Vinegar. Should be fun to watch you're reaction. You'll defiantly win a belching contest.Forget the Honey it doesn't do anything.

Might as well drink water. And tell the person that told you to do this to stop pulling your leg!
