I only took it before bed, and it really did seem to help my get a good nights sleep. Either it kept me calm at night in general, or did something to help my blood Sugar remain normal then. It was, essentially, the same sleep I'd get on a very low carb diet.
The real challenge is finding the exact right amount to allow the flush, without that turning into a burn. And the amount seems to change daily, so not sure how to handle that. It's such and fine, fincky line. So it's no longer part of my nightly routine.
