Poor Wiz~ the flat tasting alka seltzer *blech* prep; but as we said at the GTG; you need to get it done. I'm proud of ya; you can do it.
I plug my nose when I drink a glassful and then w/o taking a breath, I pop a peppermint in my mouth for a couple of seconds. Helps a little, plus keep the mixture in the fridge, as it is supposed to taste better cold.
Will be thinking of you and let us know how the tests went. Take care my lil Wiz friend.
