Liquid diet ideas

So I've read all the fun things I can do with my protein shakes.  But what about the pre-op liquid diet?  I need ideas girls.  I have some syrups I can add (Carmel and irish cream and raspberry) but what about something fun?  Help?! 

The only thing I was told about pre-op is protein coffee...made with decaf of course

**Like** 

And, protein chai tea latte.
