I've been looking at a product called 'moon brew' they listed this supplement for one to stop you mind from racing at night. Dosage says 1. I found that the first few weeks of taking this vitamin, that it did slow my racing thoughts and I've been able to get back to sleep. But, I feel I have hit a plateau and have increased the dose to 2 and it has silenced my mind! With said increase, I'm sleeping better and I've also noticed a case of vertigo. This could be hormonal based but the correlation between the time I increased it and the dizziness, I can't help but feel this vitamin is causing it. Something to pay attention to.

I work nights so I don’t get as much serotonin and I should. One of these before bed has me feeling like a human being and I love it.
