Had second fill yesterday and all has been fine until today. After I drank protein in shake for lunch I began to have extreme pain on left side and what seemed like horrible gas pain this went on for two hours and stopped. So bad left work.Could it be cuz shake was cold and I drank too fast?

you might have swallowed a bunch of air, if it gets under the band it actually causes your stomach to distend and it is very painful. My doctor told me to take a gas x like an after dinner mint with each meal to help prevent this.
