Another quick personal life update - I've been doing the gluten-free thing for a couple of months now. I don't think I'm intolerant, but I just wanted to try it because I've heard great things about people feeling more energetic and healthier after eliminating gluten from their diets. I thought it would be worth a shot since I'd been feeling pretty sluggish and bleh.
Now, two months later, I really do feel more energetic from day to day. And my clothes fit a little better too. I'll also be the first to admit that I need to do more research on this diet before I can say I'm completely gluten-free. Food can be overly complicated sometimes, and I need to get better about planning meals around the simple stuff, i.e. real food. Hopefully becoming gluten-free will help me get on the right track.
