sensitive stomach? and still ok?

I posted this on the complications board but thought I'd also appreciate feedback from people who haven't had lapband complications: For the past several years now, I've had what I call a sensitive stomach--if something doesn't set quite right and if it makes me feel sick, up it comes. I'm not "scarf and barf"-ing. It's just that sometimes when I get anxious or nervous or I'm in a big hurry (like right before running off to work), I'll feel yucky and I throw up. It's quick, painless, and I always feel better right away. Also, certain foods seem to calm my stomach while others agitate it and just don't seem to agree with me (for example, every protien drink with whey in it has had to come back up). Since lapband changes the configuration of the stomach, I've been worrying lately about my prognosis for success. Frankly, to ease my mind, I'd love to hear from anyone who's doing just fine--sensitive stomach and all! Thanks for your reply.
