Let's see...I don't drink any kind of soda at all and I hate artificial sweeteners. I don't drink coffee - just tea, mainly green tea. My immune system seems strong - I haven't gotten a cold or flu in about 3 years, despite being exposed to sick people.

I'm not sure about gluten...never considered it.

I have been pretty tired lately, too. I am getting 8 hours of sleep and wake up tired and achey - not every single day, but definitely the last week or so. I may go to the docs and see if there is some blood work she can do to see if there is something going on.
