Oh please stop drinking diet drinks, they are bad for you, drink water instead, i know it does not taste as good but better for you, i hope it is nothing to worry about my dear friend, it might well be a reaction to your medication, and ease as times goes on,thinking of you and hoping there is a good outcome, you don't need anymore health issues right now.

David i had heard diet drinks make you hungry and some people drink them hoping it will help their weight loss, but in actual fact it adds to it, just something to think on.
