Resolving to lose weight in 2010? Don’t let your drinking habit get in the way!

The Liberty Hotel in Boston is hosting informative (and delicious) “Finally Fridays,” serving up “Sleek Cocktails” with 150 calories or fewer.

One of three of the hotels “beveragistas” (a slimmer, sexier version of mixologist?), shakes up drinks like the Malibu Lift (Malibu Rum, Truvia (a brand of stevia, a plant-derived no-calorie sweetener) infused green tea, orange juice, lemon, and a coconut-dusted rim) and the Hydrate (cucumber vodka, watermelon puree, lime juice, and Truvia) all while onlookers sip samples and unwind.

Drinks cost $12 but the inspiration and recipes you can take home for free. Just don’t break any other resolutions while you’re under the influence.
