I have tried every non-dairy milk substitute out there as I became lactose intolerant recently. I thought I had a winner with coconut milk but that just delayed the pain in my belly and kept me uncomfortably bloated. I am happy to report that I found a really tasty substitute called, Mimic Creme, and it's totally non-dairy!! I use the Hazelnut Biscotti flavor for my coffee and it's yummy!!! I wanted to share this jewel in case there are others like me that were tired of drinking black coffee because you can't tolerate milk or don't like the other alternatives.
Here's a link to the website:

I do not have any affiliations with the company, I just wanted to share a good find. Btw, I got mine at Whole Foods.
