Longer than 2 week Pre-Op Diet?

[DallasM 4]

So I've done all my required pre-op testing appointments and on my first visit with my NUT, the Dr. Instructed her to put me on a clear liquid diet starting now. I've done well in the last month since my first consultation with the surgeon, I even managed to lose 10 lbs. I'm on day 3 of liquids and doing ok, but I can't wrap my mind around how long this will take. I don't have a surgery date yet, and as far as I know, my file hasn't been submitted to insurance yet. Has anybody had to do a longer than normal pre-op diet?
