Anyone having hard time with liquid diet? Did anyone cheat? I want this so bad but im getting very hungry. Anyone have any advice? ??

I started to " practice" the pre surgery diet about two months ago, and started the 14 day, I am scheduled for sleeve in the 10th, I lost 22 lbs since March, and I don't know what I am down to since the pre diet, lots of cakes, donuts, carry out food at work last two weeks (I work in a hospital) and I was able to avoid any temptation, then last night after everyone headed to bed I was getting my water and there was some left over burger and pizza from my family's dinner so I took a few bites, well I paid for it, u didn't feel that great for awhile after, and had to use the bathroom first thing this morning, so I will not cheat again.......
