I tried this on a whim based on a free sample offer and ended up loving it. I had an issue at one point and customer service was extremely helpful. I also tried focus which didn't do much for me personally, but the sleep version absolutely helps me sleep better. Definitely recommend at least giving it a shot.
What can I say? I’m hooked! I use the green ones during the day to help me focus and the sleep ones to wind down before bed. Fantastic product!
