The taste is awful. It tastes like artificial cough syrup, its honestly so bad. I wish they just kept the tart cherry flavor.

Works great

seems to work very well. since taking this product and ashwagandah at night, I've been getting full night sleep. I have no issue with the flavor.

At first, I didn't feel like this worked that well. But the more I take it, the better it works. My husband sleeps better too.

Horrible

This tastes STRAIGHT like cough syrup. I drank a 1/3 of my cup and became VIOLENTLY nauseous.
