I would def do the pretend thing - you can "pretend" to drink:

Vodka, soda and lime - just have soda and lime
Burbon and coke: just have coke
Barcardi and OJ - just have OJ
Fruit ****tails - just have the fruit and juice!!

Word up the barman and they can help you!! Oh just remembered - coke isn't a great idea while pregnant. Well anything with soda or lemonade. Or allergies to alcohol - that's prob taking it abit far!
