Pretty much the exact same experience as Brockel. Did it for 90+ days Jan - mid April. Came off of it a few weeks ago and got a severe migraine the second week. Normally am good for about a migraine every couple of weeks, but did not have one the entire time on carnivore. Will definitely be doing it again. Never felt or slept better.
It definitely changed my sleep for the better. I use to sleep terrible. Now I hit the pillow and I’m out until 4:30 am like clock work
