Yeah, good luck with it! Travelling and all liquid ... yeesh!!
I am not following any specific gluten-free plan, still following Dr. Schwarzbein's program, and now avoiding all sources of gluten along with casein for the next few weeks. Then I'll add back in the casein (butter, cream, yogurt, cottage cheese, cheese) and see how I react. But the gluten thing is going to be permanent for me. I've been experimenting a little over the last month or so and notice a definite reaction (increased aches and pains, water retention, fatigue). The reason to eliminate casein initially too is that gluten and casein are very similarly structured molecularly, and sometimes when you eliminate gluten, the body confuses casein and you will get the same reactions. Hopefully that will not be permanent as I love my dairy products and really miss them!!
