hi - the reason for the liquids is that so that NO particle of food gets stuck in the internal stitches. If it does, food can leak into your internals and it is life threatening. Also, your stomach can't weight bare heavy foods, another reason.
A nurse in my hospital told me that a lady had pizza a couple of days after she was discharged.
A piece of pineapple became lodged in her internal sutures (stitches) and she was rushed to emergency.
She then spent 79 days in hospital recovering... and the doctors struggled to keep up with the damage she had done to herself.
I know it's hard. I'm at the tail end of 'liquid only' and I've learned to be creative.
Craving real food but the words "LIFE THREATENING" keep me focused.
If think it's a psych thing, a habit - seek a counsellor help.
But for your life and that of your family, stick to liquids for 2 weeks post-op.
Good luck
