Two things are happening right now. One, your stomach is a funnel for most liquids, including the thicker ones. Two, all the nerves that used to tell you when you were full, were just cut. So adhere to the guidelines set forth for you. The next few weeks will likely be difficult for you and you will experience hunger again. You wont get to feel real restriction until you are in coarse purees or soft foods so treat your new tummy well. =)
