Hey,
Oddly I was waiting for this question :)
Currently I am on shakes with only 1 meal a day.
It's not a long term solution and can cause some other health problems.
The surgery is a great boost that will allow me to have a regular controlled diet (and allow me to enjoy food in smaller potions) as opposed to now where I have to be very strict and be on shakes.

The surgery is just another tool in the war chest.
