Definitely eat slowly, and when you thinking you are eating slow enough then slow down a little more lol. I have concentrated on eating my food slowly since my surgery, and in the 15 months since have yet to throw up from eating. I concentrate on keeping it slow and generally know about how much I can eat now. Shortly after surgery though where you are still learning your new stomach it is a little more difficult. I found for me that I just concentrated on staying slow, and at the first sign of any discomfort I stopped eating. What I found was that the discomfort was generally a small amount of gas trying to work it’s way out of my stomach as the stomach became full. Following this method has worked great, and as I said I have been lucky enough to have not thrown up since my surgery. I read all the horror stories of people constantly throwing up while eating, and that was all it took to make me really concentrate on this part of my recovery and new eating habits.
