Angela, I had my surgery done in the UK and here we are only on clear liquid for 1 day after surgery then we go on to liquidised food like mashed potato fish and some sort of sauce whizzed in the blender, really soft egg mushed up and yes smooth yoghurt, thin oatmeal, custard, and things like that , we don't do the protein shakes at all. I am now 3 weeks out and I am moving on to mashed food gradually that is any kind of food that can be mashed down with a fork, fish, omelette, minced meat and again add some sauce or gravey to make it go down easily if you have any problems.
Hope this helps,
I find it really helpfull reading other peoples posts on here it has answered all my questions and worries, so glad I found it !
