Has anyone else experienced a change in their sleeping?

I used to be the night owl who could not sleep until the wee hours of the morning. My DH was always up before me. I would drag myself out of bed every morning feeling like an elephant had stomped me. Never in a good mood.

After starting Atkins a little over a month ago, I find it hard to stay
awake past 10pm. And I wake up very early feeling fine-actually able to carry on a conversation

This is an added benefit I never expected.
