Although a diet root beer with a bit of heavy cream has a root beer float kind of taste.

And there are MANY low carb non sweet snacks... these are just a few I thought of.

microwaved pepperoni chips
string cheese (remember though only 3-4 oz daily)
veggies dipped in full fat (low carb) dressings or stuffed with a little cream cheese
cup of decaf or herbal tea
tuna, shrimp, chicken salads
deviled eggs

Just eat and get past the craving and you'll do fine.
