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 a 2 1/2 year old 60 pound German wirehair pointer.  We feed this food during hunting season due to his increased metabolic needs.  He burns so many calories, he eats 8 cups of this food a day (with zeal).  We use the large bites to help keep the tarter and plaque off of his teeth (and to slow his eating).  Due to the high quality of this food, he can keep up his energy, keep his weight up, and recover more quickly from scrapes/bumps from running the field.  Our vet's exact words were, "Your dog is an example of perfect health."  You may think the price on this food is high, but it is worth it.  You get what you pay for.  Also, consider the canned version of this food.  It is a nice way to feed/hydrate a dog after a long day hunting - just give them an hour to settle down first.  On a side note, we feed Diamond Naturals Beef and Rice in the off season.  We have no digestive issues transitioning from one to the other (we switch over a period of a few weeks).

Ex Output:
Positive

I began purchasing this tea years ago and looked forward to it each year. For the past two years I was unable to locate it in my local stores so I was elated to find it at Amazon. It tastes like cinnamon and red candy apples to me. I love it!

Positive
