I'm scheduled for surgery on December 17th, and I'm concerned how I'm going to eat while on the road. I travel by plane 3 days a week, and anyone who does so knows that airports are poor nutrition outlets.

Any ideas what to pack a carry on? What do you eat? How do you handle the protein shakes? etc.

any advice would be helpful

While I don't travel for a living, one of my goals has been to make everything as easy as possible (I'm seriously lazy). Once you're far enough along you can take advantage of foods like jerky, cheese, nuts and other things for snacks. Since I had to make my shakes at work every day, I bought two things: a blender ball bottle and a small "smoothie" blender with travel cups. I would put a serving's worth of protein powder in an extra small ziploc container or bag and bring along any extras (fruit, extract) with me. As long as you can access water (ice, too!) and a power outlet you're in business. If you're in a rush, milk and protein powder in the blender bottle and you're good to go.
