Good for you for not giving up and figuring out the problem. I cannot eat nuts except almonds because I have big portion control issues.
I have the same issue with berries so be forewarned. You can probably do chayote squash with cinnamon and Splenda to put on your yogurt. Some places call it cho-cho. I love it and it has a lower carb count than berries. I just posted a recipe in the dessert section of the Recipes forum.
