Kay it varies a lot I think, from person to person and from day to day. There are still some days where I can't manage 1/2 a weetabix! At first I could manage about 4 spoons, but now I could manage a small bowl....and thinner soup more than that.
I used ice cube bags. If its too much, it won't break your heart to chuck a bit away. If not, you can do another one.
It's getting exciting. Any news yet?
