    Great recipe! However, there’s a key ingredient you’re missing. When I was working at sonic, ocean water was made by mixing our blue coconut syrup with sprite. In fact, almost all of our special drinks use sprite as a base!

    This recipe states that it makes (1) serving. If that’s so, I’d consume ONE WHOLE CUP OF SUGAR if I made this drink for myself! I can’t believe it, so PLEASE tell me that I misunderstood the recipe! BTW, “Sonic” is well noted for it’s unhealthy & fattening food, so I don’t know why anyone would care to eat there, nor to want any of their recipes….just sayin’….

    I had to stop using Splenda because it causes my vision to blur, I think it dehydrates but I do wish I could use it without concern. I use Diabetic version of Whey Low because it is lactose based but has a lower glycemic index count than regular Whey Low ( ordered online). It’s called Whey Low D and dissolves best in hot liquid but can then be chilled. They have a wonderful brown sugar sub called Whey LowGold), but is not necessarily what diabetics should choose. Sometimes I combine stevia and Whey Low D.

    I love Sonic Drive Inn’s Happy Hour drinks! I fortunately live in Texas and there are plenty if Sonic Drive Ins! Yes, I do look forward to and partake in their drinks at least 2-3 times a week! Their mozzarella sticks (cheese sticks) are the best also! I asked a Sonic associate who made my ocean water drink what exactly is in that drink and she said it was simply lemon lime soda (Sprite or ginger-ale) and blue-coconut syrup, like they use on snow balls or cones!

    Dear Stephanie, I live in a place without a Sonic, I know, I can’t believe it either. I would love this drink, but, I have type 2 diabetes. Would you possibly have a recipe that uses artificial sweeteners? I would like to thank you for all your copyKats.


    • Stephanie

      I am sorry you don’t live near a Sonic. You could try making the syrup, I would construct it the same way, replacing the sugar with the sweetener of your choice, then you could use a diet lemon-lime soda.

      • Mike

        I’m like Phyllis – Type 2 diabetes – so I don’t drink sugar sodas or anything similar, but I used to date a woman who loved to mix Tuaca, a naturally flavored brandy liqueur, with Ocean Water. I’ve never been much of a drinker, but it really was tasty.

    • KD Bingaman

      Try replacing the water, sugar, and coconut extract in the syrup with bottled coconut water sweetened with Splenda drops (5 drops = 1 tsp of sugar). Splenda, of course, is a natural sweetener (sucrose), and it won’t have the bad effect of sugar (glucose) on diabetic conditions. Add coloring as indicated.
      Replace the lemon-lime soda with natural sparkling mineral water, add in 1 part juice (about 25%) from natural lemons/limes, sweeten with Splenda if necessary (about 5 drops).

      • Bug

        Splenda (sucralose) is NOT natural; however, it is artificial. Maybe you should look up how it was discovered. Stevia is a natural herb that is sweet. Go with Stevia!
