I think I've made a huge discovery on the trip.
At the beginning, 'normal' amounts of fat in my diet caused indigestion (like the beginning of a gall bladder attack.)
One of the hosts at a B&B was into nutrition and when I asked for just a small amount of cheese in my omelet due to fat causing indigestion, she said my liver should have easily covered for the lack of gall bladder and had I considered adding a probiotic to my supplement regimen? Since I had brought extras with me (they are part of dh's regimen and I use them if I get GI illness when I travel), I added one to my routine each day.
Slowly I added a bit more fat into the diet. Yesterday was a 'bad' day (cheesecake, bacon, butter, peanuts) and had no reaction at all.
In addition, even when I don't have high fat in my diet, my regularity has returned. Still don't know if that is due to the higher carb (my regularity disappeared when I upped my protein/carb ratio no matter how much water I'd consume in a day) or if it is the extra fat in my diet, or some other reason, but it has been a relief to be regular for the rest of the trip.
When I get home, I'll be able to figure out for sure if the probiotic helps with the second point as well as the first but in the meantime, it has been great to not be too worried about how much fat something is cooked with (when my pan fried cod made me sick, I was worried about how I'd manage the trip since broiled fish wasn't on the menus, just deep fried and pan fried.
