watermelon-cucumber cooler - for nonalcoholic version, use pineapple juice flavored with almond extract for rum. for sugarless version, substitute 1/4 c stevia powder for sugar in syrup.
To boost weight loss (and it's just yummy) - 2L water, 1 medium cucumber, 1 lemon, 10-12 mint leaves. steep overnight in fridge and drink every day. Also great for general detox--including clear skin!
