Chronic SBO even after surgery and low residue diet

Hello, I've been suffering from SBO for over 2 decades now, the 1st 'diagnosed' was when I was 24 thou I am sure I had obstructions before that. It was originally cause when I had surgery as an infant for Pyloric Stinosis ( a very rare disease that seals the tube leading from your stomach to large intestine that apparently only happens to 1 of every 10'000 first born males) So when at 24 I was in the ER they thought at 1st it was a stomach flu, gave me an iv to rehydrate me, sent me home. 2 days later I was back for emergency surgery. It was SBO.
My GI put me on a low residue diet but I still get the obstructions....more recent but I did go over 2 years without one at all. It's odd, I'm a Chef and sailor, when I'm away at sea I am fine, no obstructions, but the past 3 times I'm home I seem to get one?! I'm trying to nail it down....I avoid all veggies and most fruits ( unless in a shake) Maybe its size of meals or more take out? I find on the boat I hardly eat anything and often have to remind myself to eat! Comes with being a Chef honestly, I cook all day when I'm done I don't want to even look at food lol. I made smoked ribs, pork belly on my home smoker two nights ago....I was fine then had the munchies at 2 am, I had 2 pieces of the smoked pork belly some potato salad ...then 2 hours later the cramping started...could it be the pork belly? to fatty? to rich or the onions in the potatoe salad? Should I eat at home more like I do on the boat? Very small meals avoid take out ect? any help would be great thank you all.
