He sounds so sweet! You might think about reminding him that you need to exercise to help your recovery. You could tell your Mom that you and your husband need to figure out your "new normal" on your own, and reassure her that your husband is taking good care of you. (And you'd love to see her after you've healed so that you can do more things together.)
I'm a year and a half out. Per guidance, I had avoided alcohol and carbonation. My daughter and I we're on a cruise, and I decided to enjoy a mimosa with her on our balcony. I had about half a glass when the pain hit my stomach-- Lesson learned for me-- no more than a sip of bubbles. And no more than a sip of alcohol.
