I tried the product for a few days. It did not help me with any Lucid Dreams at all. I tried it for few days, not every day. Nothing happened. All I got was a headache the next day..like a hangover headache,  It tastes bitter like others have mentioned but nothing that I can't handle. The bitterness was no big deal for me.

Ex Output:
Negative

I have had Green Mountain coffee before, but had not tried the French Roast.  I am just realizing that there is a taste difference between different manufacturers, even with the same types of roasts.  The Green Mountain French Roast has the flavor I like and was expecting.  The price was reasonable and my order shipped quickly.  My only disappointment was in the shipping packaging.  I knew that I was ordering 2 boxes of K-cups but was surprised to see how big the shipping box was.  There was room for 3 boxes, with the extra space filled with bubble-wrap, which seems wasteful to me.  But on the whole, I am very happy with my coffee!

Ex Output:
Positive

I purchased two types, the original and the salt and vinegar. The original tasted burned, they were very tan/brown in color.  The vinegar were very sour.  Both cases were trashed & Amazon handled credit asap.  I have purchased these in grocery stores & airports and never had this quality problem.  These are pricey that's why I jumped at the great price Amazon offered this product.  Does Amazon got seconds?

Ex Output:

Negative
