Pretty much what everyone else said.

Alcohol is an acquired taste. Stay away from the cheap stuff, and make your drinks not that strong.

Margaritas could be a good start.. They're sweet, but if you knock the salt that rims the glass into it and squeeze a couple of lime slices , that will cut the sweetness down quite a bit... At the top at least.

Restaurants don't typically make margaritas that strong (they wanna make they money after all), so you won't taste any hard liquor.
