Jan, some of the Diet Rite (not the cola, sadly) is really, really good. Their lemonade is terrific, for example. See if you can find flavors besides cola.

Can you handle Splenda? I loooooove Propel flavored water. I'm pretty sure it has Splenda and not aspartame, but I'm not positive.

I hope you figure out what's going on and that it turns out to be perfectly minor!

Love, Candy
