I was a little disappointed because the lemon flavor was weaker than I had imagined. <br>It was included as a service with the product I purchased, but I don't think it's worth spending money on...

I noticed a difference in how refreshed I felt after waking up after drinking Brain Sleep Water compared to when I went to bed without drinking it!
At first, I was skeptical, wondering if it was just my imagination, but after a week of taking it, I decided to try going to bed without it, and when I woke up, I felt drowsy and unrefreshed. I was also surprised that when I slept after taking it, I felt refreshed even though I slept for a short time.
It suited me so well that I ordered a regular subscription.

I feel like the quality of my sleep is different on days when I drink it and days when I don't.

It has a lemony flavor and is delicious!!

It's easy to drink, not too sweet, and doesn't leave a residue in your mouth even if you drink it before going to bed.
I didn't notice any particular change in my sleep.
If you drink it right before going to bed, you will wake up in the middle of the night, so make sure to drink it with plenty of time to spare.
The next morning, anyway, was different.
I woke up feeling refreshed.
It may just be my imagination, but I feel refreshed the next day.
