[EX Q]: Google "propylene glycol" to find out why.  I bought this product, along with several others, without running the ingredients by my wife first (a nurse of 30 years) she was surprised when she noticed it.. we went a googling, and poured my $50 order down the drain afterwards.  There's "pure" and then there's "not so much".....  from the website:  [...]  Propylene Glycol  A cosmetic form of mineral oil found in automatic brake and hydraulic fluid and industrial antifreeze. In the skin and hair, propylene glycol works as a humescent, which causes retention of moisture content of skin or cosmetic products by preventing the escape of moisture or water. The Material Safety Data Sheet warns users to avoid skin contact with propylene glycol as this strong skin irritant can cause liver abnormalities and kidney damage. Also used in:    Tyre sealant   Rubber cleaner   De-icer   Stain removers   Fabric softener   Degreaser   Paint   Adhesive   Wallpaper stripper  I wrote the company about this concern and they never responded....
[EX A]: Negative

[EX Q]: Was skeptical about the quality of hot chocolate from a K cup but Grove Square is amazing.  It is just as good as making it from scratch but without the fuss.  The milk chocolate is mild, the dark has enough bite to make it interesting and the peppermint is perfect for after dinner.
[EX A]: Positive

[EX Q]: 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 A]:
Negative
