Not at all. Like I said I've only been taking it 3 days but no lie, it's been everything I bought it for and more. That usually doesn't happen for me that often or that fast. Do a little research on the 3 brains (mind, heart and gut) and it'll make sense. It was $23. It says take 1-3 daily with food. Like all the others, I start at minimum. I'm taking one with my egg and avocado.Sleep is one of my biggest issues, I have others, but they are not as immediate as losing sleep every nite. Not being nosey, but do you mind sharing which supplement?
