Hi I had the Gastrograph after I had my Sleeve, it was to test there was no leaks. Bit like being on a roller coaster, you start standing with a large xray type plate behind you then a plate comes on front, then they lift you up so you are lying on your back and ask you to move onto your side, this was the worst part of my opp lol. Thought I was going to be sick, but I am a bit claustraphobic so it could have been that.
