Well, you certainly have done a lot! I think you've exhausted my ideas. : ) My husband took the Primal Defense for awhile and then we heard some bad stuff about the probiotics that use the soil organisms. You might want to google that and see if that's the way you want to go. And remember, the probiotic is for life. Don't just use it for awhile and think you can retain all the good bacteria you need.
I'll be watching this thread to see if I can learn from someone else!
Your European descent probably favors use of dairy more than most other races. I think the lowest percentage of dairy allergy is Dutch. I am all Scandinavian and although not allergic to dairy, I do feel much, much better without it.
Wish I had some mind-blowing advice for you - you've done a great job so far!
