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: Product was never received nor money returned. Four requests have been ignored. I will probably never again order anything through Twang or from Amazon. Also, I will spread the word about these sites.

A: Negative
