I too was on a liquid diet 2 weeks prior to surgery...I quit having my last meal as it seems that's all i did for a month prior to this. I was so afraid my liver wouldn't shrink and they would have to do an open proceedure I totally stuck to the liquids. For me my "last" meal was important...but not as important as having my surgery go well.
This is totally your call though...I hope all works out for you good luck!!!
