I gotta do what????

Before receiving surgery my doctor requires that we all go through a pre-op class.  The class covered things from nutrition, exercise, what to expect after surgery and even guidance from a therapist.  There is a lot to learn and I have to say I'm glad I have a few weeks to review and practice some of the them.

I have heard the term 30-20-30  before but wasn't quite sure what it meant.  Now I know.  Actually, I sort of figured it out beforehand.  I've been trying to eat for 20 minutes.  I even set a timer to help me, but that is very tough...especially for someone who is used to gobbling my food quicker than Usain  Bolt runs. 

How have you handled the 30-20-30 rule?  I'd like to know.  Comments, please.
