it's odd that you would only be allergic to almonds and not walnuts. How about pecans? Or other nuts like macadamias? Peanuts I know are problematic.

I was in Mac's Milk (the canadian equivalent of 7-11...not too sure where you are) last week and noticed they carried some organic jerky...which really surprised me. I can't recall the brand, because I ate it and then thre out the wrapper! But I will go back and check...maybe something for you to look into in your area.

Can you eat seafood or fish? I know it's hard to find that organic, though.

I think with the cider vinegar, low-carb wise, I would use caution and read the label. As for your ulcers, well, I can't advise you on that...YMMV. You may need to test it out to see what your own results are.
