Faking It

We go to a lot of house parties and as I'm only 5 weeks along I don't want to share yet. In order to avoid the "why are you drinking water... ARE YOU PREGNANT??" questions/accusations that always abound, I faked my cocktails with a virgin tequila sunrise. Needless to say I am sick to death of orange juice and cranberry juice today. 
Tricky part came when everyone was doing shots and I had to discretely disappear for awhile. 
My main question is,  what else can I concoct  to fake it for a few more weeks? I read of other "mock tails" but a lot of them included a blender or milk - not really helpful.
