The pre-op diet is really hard, especially for those who have a full liquid version! You're essentially putting your body through the start of the post-op phases, without the benefits that come from the surgery. If we were all able to stick to diets perfectly, none of us would be here. You made a mistake, you haven't failed. That said, do your best to stick to it the rest of the way, for your own safety and post-op success. Sometimes remembering that it's only temporary helps a lot.
