I recently tried one of those crazy cleanse diets. For two weeks, I ate entire fields of kale and schools of salmon, and I avoided alcohol, gluten, sugar, and dairy. (I also moaned to anyone who'd listen.)

And while it was a given that I'd avoid the free bagels and bundt cake in the office kitchen, the daily ritual I did keep was my morning cup of coffee (with cream). Giving up chocolate chip cookies and cheeseburgers was reasonably easy; abandoning my creamy coffee was not even a consideration. And I know I'm not alone in this: Whether it's three cans of soda, a couple glasses of wine, or that iconic green and white cup filled with frothy caramel macchiato, sometimes our drink addictions are even harder to resist than free Halloween candy.

And the so-called "diet drinks" aren't any better. "Both sugary drinks and zero-calorie drinks with artificial sweeteners like Aspartame contribute to weight gain," says Peggy Kotsopoulos, nutritionist and author of "Must Have Been Something I Ate." So what does that leave me with � water? I couldn't accept it.

Skip ahead for 8 diet drinks you'll love.

So I turned to nutritionists and healthy-eating experts, and asked them for the most diet-friendly, nutritious alternatives to the delicious, addictive, high-calorie beverages we all love. I asked them what they drink and what their families drink. And, most importantly, I asked what I should have instead of my beloved cup of coffee with cream. So, the next time you go on a diet, pick up these diet drinks that will actually help your cause.

... try drinking your vegetables.

Sorry, but your beloved breakfast smoothie probably isn't very diet-friendly. If you're blending together a bunch of fruit and not much else, the resulting drink is high in calories and not particularly filling. And we've all heard that breakfast is the most important meal of the day, but it really is true says Terry Walters, nutrition expert and author of "Clean Food."

So to make your go-to smoothie a bit more nutritious, Walters has a simple solution: Throw in some vegetables. "Follow this rule when using a blender: For every fruit that goes in, add a vegetable," she says. For a breakfast smoothie that will keep you full until the afternoon, she suggests using frozen peaches, banana, and as much kale as you can squeeze into the container. (Kale is a super food that contains vitamins, antioxidants and cancer-fighting phytonutrients -- and it has tons of fiber, but only 36 calories per cup.) Blend it with rice milk, ice, and a spoonful of maple syrup.

... try coconut milk with raw cacao.

I hate the thought of giving up my morning cup of coffee so much that I told the nutritionists a viable substitute would need to be even creamier and more delicious. They had me at chocolate. Walters recommends whipping up a drink with high-quality chocolate, which has a small amount of natural caffeine. "Raw cacao is the best," she says. "It's an antioxidant, and it's high in magnesium, which helps your body absorb nutrients." She suggests blending coconut milk, half a banana, raw cocoa nibs, and ice for a diet drink that's like a cross between a blended coffee and a chocolate milkshake.

...try having only one glass of wine -- and make it red.

The average glass of wine has about a hundred calories, which is fine if you only have one. But when one turns into three or four, those numbers start to add up quickly. "There's nothing wrong with one glass of wine," says Kotsopoulos. "But choose red -- it tends to be lower in sugar and higher in antioxidants [than white]."

...have vodka with coconut water.

Most frozen margaritas have hundreds of calories because they're loaded with sugar. If you're going to indulge in a cocktail, Kotsopoulos says the best rule to follow is to always be in control of the amount of sugar that's in the cup -- even if it's fruit. "Squeeze the lime yourself," she says. "You want to know exactly what's going into that drink." One of her favorite combinations is coconut water and vodka. "The coconut water has electrolytes, which rehydrate you," she explains. "I like to say that you 'tox and detox' -- which means you're a lot less likely to be hung over."
