Hi Katina and welcome to the forum!
I don't have the cabbage soup diet...but, I do have a Liquid Diet 10 days before my surgery on May 26th that I will be doing-- as well as a bowel prep
the day before surgery.
Congrats on being a Loser soon!!! Hopefully you will find a support group in person or online in your area, with other people that have the same surgeon.
