Hey there! I am just over a year post op and I have found that even up to around the 6-8 month mark eggs just didn't sit so well on my stomach anymore. It sounds to me like you are doing all the right things- eating slowly, chewing well, etc- so it really may just be the eggs themselves. Try adding a little milk or Greek yogurt and whisking them very well to scramble, it makes them lighter and fluffier. If that's still giving you problems I found that hard boiled (no yolks just yet, they sit heavy) is a somewhat better texture for me personally.
When you try other foods do you have the same feeling? If so, it could just be an adjustment period as your stomach learns to digest again. Some foods definitely take more time than others to re-introduce. For me that included eggs, chicken, beef, nuts, and dark green vegetables like broccoli and spinach (except in smoothies.)
