I think peppermint tea and green tea is allowed, please check tho as Im not a cdc (yet!!)
You can add pepper and tabasco and things like that to spice your soup up, no salt on CD though at all.
And also tablet sweetners are allowed too.
Some use a teaspoon of Vanilla Shake as a type of coffee mate, I havent tried it as I dont do coffee!!!
Hope this helps x
