I picked up some of the Golden Circle brand diet soft drinks yesterday. I've been at this now for about a week and felt like a treat. So here is what I did:

I poured half a glass of really cold diet Lemon & Lime flavour.
Then I added half a serve (50 mL) of Peters carbohydrate modified ice cream.

It frothed up as I ate it with a spoon and made a really yummy treat with just less than 3 carbs

Go ahead and try it!

p.s. As a newbie, I just want to say thanks to everyone for the great ideas, advice and support. Cheers!
