I get that public enemy no 1 is drinking before and after eating. We're big soup eaters so how does this apply? A bit of sushi with some miso soup? What's difference between this and drinking water while eating?

I have learned that you have to follow the INSTRUCTIONS!

Thanks for the input. I look forward to other constructive feedback as well.

I think it relates to a couple of things (note I said 'think' - just my thoughts)

- if you drink too soon after eating, it will just push the food through your stomach too quickly and could impact on the Vitamins your body absorbs. If it's pushing through undigested food, it could also impact on your bowel movements?

- if you eat your full quota of food and then add liquid you risk stretching your stomach. This is my main concern at the moment, I haven't just gone through surgery to stretch my stomach at this early stage!

There's possibly other reasons and if so, hopefully someone will post them here but hope my thoughts help a little......
