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

Ex Input:
I decided to try this formula for my baby since he started being very gassy. However, this formula made him more gassy...the formula is very thick and produces a lot of bubbles that gets fed to the baby. I tried to make the formula with anticipation to let the bubbles disolve but that didn't work.

Ex Output:
Negative

I've been using this for the past few years, but this year, I've not only found the bugs, but I actually have a WEED that grew and punctured through the bag! I kept wondering where all the weeds were coming from in my planter boxes, and now I know!

Negative
