Hi I had my op in Nov and I used to make a banana and mango and yoghurt with Water and ice smoothie for my breekie then I would have a yoghurt drink 2 hours later then 1/2 tin of soup 2 hours later then 1/2 tin of soup 2 hours later then a yoghurt and then another 1/2 tin of soup and then try to get the water in aswell. it was quiet hard in the first couple of weeks to get everything in I felt I couldn't go to bed early cause I hadn't had enough lol. Good luck with your surgery hope all goes well x
