Kiya, can you have Coolwhip? You can make yourself a float with frozen coolwhip and diet A&W rootbeer. Or pick your flavors according to what you like and can have. There's a possible substitute for ice cream. Can you have yogurt? Frozen yogurt is just as good as ice cream, I think, but I'm not sure all of what is on your allergy list. If it's dairy, stick with the coolwhip or try a sorbet with just fruit and no milk. That's in the ice cream section too. How about soy-based ice cream substitutes? Try a health food store for those. Some grocery stores have them too, probably in the health food or specialty food sections.
