Q: I decided to purchase this product based on a blog by one of the supplement oriented doctors on the internet, hyping erythritol as superior to xylitol, which I use regularly and find the closest to sugar in taste with almost no aftertaste and no side effects to my knowledge.  The problem I find with erythritol is its lack of flavor.  On cereal, I barely notice any real sweetness, even when I put as much as a tablespoon and a half on a normal size bowl.  When I use Ideal, the name of the xylitol brand I use, it has the same sweetness as sugar in the same proportion.  Don't get me wrong, erythritol isn't unpleasant, it just has very little sweetness relative to how much you use.  Not worth the price unless you want just a hint of sweetness compared to what you get with sugar or xylitol.

A: Negative

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.

A: Negative

Q: I was disappointed when I received this shipment, as the seaweed contains MSG, and it's not listed as an ingredient. Amazon was very gracious and refunded me the amount of purchase.
