I've gotten hooked on drinking protein smoothies in the morning. Basically just a fruit smoothie but I make them with a couple scoops of protein powder and some ground flax seed. Those ingredients come in fairly large containers from the health food store. If I just take what I need packed in baggies or other containers, I'm afraid that if I get the red light at customs they're going to think I'm smuggling in some "illegal substances." What does the collective wisdom think?
