Rebel Ice Cream?

Has anyone tried this ice cream? I have such a sweet tooth and it pains me to not have any dessert. Ice cream is my absolute favorite as well.

I was window shopping online and saw these ice cream on the sugar free section. The reviews look great, but I need someone with experience on having this treat while dealing with this diagnosis to really understand if this is doable.

Also, sugar cookies? Any suggestions on what's good and what to avoid?
