I've known for awhile that I'm lactose intolerant but continued to eat dairy anyway. A few days ago I finally decided to forbid myself completely from eating dairy because I knew it was wreaking havoc with my digestive system.
An added benefit of going dairy-free is that, after just a few days, I noticed that I was in a better mood today than I have been lately. I'd originally attributed my feeling down to things like the shortening days and rainy weather, but the improvement in my mood was unmistakable. Just to be sure, I googled "dairy mood" and found this article from About.com.
