Thanks very much for your advice :-)
The soy milk is Westsoy, Unsweetened, Vanilla Soymilk. Total fat 4.5. Total Carbs: 5. Total fiber: 4.

So, even though I can have this as part of my daily allowance in carbs, I should avoid it because it's not on the specified allowed food list?

And, also, from what reading I've done, it does look like I can deduct the fiber grams from the carb grams, but I'll still wait and have this delicious drink later.

Thanks for all the support everyone :-) This is a great place.
