From what I have read this is caused by our bodies being in ketosis. You can google "insomnia caused by ketosis," but here is a link. I'm on sleep meds but still having trouble. I may try the Webber Naturals Super Sleeper that someone suggested. Other than that I don't know what to suggest. Happy to see all the great results you are all having. I'm still in my first week.

My diet "coach" told me the following:
Actually, sleep is probably an issue more with drinking all the water and getting up several times at night. Otherwise, cutting sugars from our diet helps to lower cortisol and insulin as well as decrease inflammation and sleep is improved overall.
A physician who specializes in sleep disorders is showing positive results with Ideal Protein protocol with patients with sleep apnea and other sleep disorders when fat% is lowered and the overall environment is more alkaline normal and anti inflammatory.
