I had surgery in February and did not have issues for about 2 weeks and then Pow, did it hit hard. It took me another month for it to ease. I eat pretty regular food now but will notice my stomach and gut let me know when I eat too much or something it doesn't like. I keep Galviscon around to use only if needed and eat smaller meals and snacks. I have undergone chemo and a clinical trial since surgery as a single positive node of a rarer genotype, KRAS g12c, has reared its head and I have metastasis to the liver but I am fighting. You do the same. We can change the statistics by doing whatever we can and living longer. Take it one day at a time, Stay positive and do well.
