Stay strong, the week after surgery is when you are going to have some head hunger. Esp when you see the ads or someone brings in something from a fast food joint and you smell that grease. After another week it gets ALOT easier. That first week or two post op can be rough with the liquids and Protein shakes and what not, but you should be able to mix it up a little bit, try some different broths, try maybe adding a little bit of yogurt into a shake just to change the flavor and texture, I know I was allowed to eat the NON-fruited greek yogurts during weeks 1 and 2 (pretty much plain- yuck, honey or vanilla- they were ok).
you just need to mix it up a little bit and remember why you are doing this. I am not 4 weeks out, down a total of 45lbs including the preop diet, and feel great.
Also, I am in Houston, so if you need to talk anytime or just want to pick my brain, send me a note and we can meet up. I am 26 also and live inside the loop, it helps to talk!
