First Week: Carnivore Update Sleep improved drastically. 

Keep at it dude, I'm on day 11 today and I've found it a challenge not to snack and eat the sugary stuff but like you I've managed not to. I haven't noticed any change in sleep and mine is typically pretty bad so hopefully it'll improve. I also have coffee in the morning but obviously I removed sugar from it and have it with cream instead of milk, I'll probably stop it soon too though but one step at a time. Anyway I wish you all the best with it and look forward to seeing your updates.
