Hi Lola12,
You should be able to purchase Manuka honey at most healthfood stores. I'm not sure where you live but in my neck of the woods Wholefoods Market, Mother's Market, and Sprouts Markets carry Manuka honey.
I also want to second chewing sugarless cinnamon gum after a meal, I have found it beneficial. The brand I buy at Sprouts is called SPRY and I buy it by the case.
