I like the idea, and the taste is pretty good, but the biggest problem I have is that over the past few years, I have developed a mild allergy to soya milk. It gives me a throat ache, as if I was catching a cold, after 1 hour, and lasting 4~5 hours. Drinking the product gives me the same symptom, and as a result is quite a frustrating experience.
I knew the product contained soya, but still hoped for the best. I'm currently experimenting tricks and workarounds (such as drinking a lot of water after), but I was curious if you were considering soya-free alternatives.
People without soya allergy would probably enjoy this product.
