I definitely feel this way. I was discharged a day early, and was out clipping hedges the day after that. I went from being terrified I'd have massive complications to wondering if I needed an x-ray just to prove to myself that my body was different internally. It's been very strange. I haven't encountered anything that bothered me, though I haven't tested the waters so much, avoiding sugars and high-fat foods. A lot of things I anticipated giving me troubles because of how much they were mentioned, for example eggs, haven't caused me any discomfort at all. My biggest problem is reminding myself to eat (and staying on track with vitamins when I'm so busy during a move). It's definitely been interesting!
Due to a four-day drive across the country and settling in, I have gotten a bit off-track, I'm not eating as much protein, and have been eating some carbs: it stalled my weightloss. However, I've upped my proteins and gotten back on track with vitamins and went back to losing like crazy.
