Some doctors are very lax, some are strict. Mine is pretty strict; 2 weeks liquid, 2 weeks puree/mushy, 2 weeks soft food. Only at 6 weeks does the plan allow me to try out things to see what I tolerate. I'm on week 3, the first 2 weeks were really tough, but the mushy puree stuff isn't bad at all. I'm in the same boat as you where I feel like I could tolerate pretty much anything, but if sticking to the plan gives me a lower probability of future problems then I will do it. Plus the restricted diet has helped to jump start my weight loss.
Its all about percentages I suppose, letting your stomach do very little work and sit still while it heals allows the band to stay in place better long term, which lowers the probabilty of slips and other complications.
