Exactly. I quit smoking and (temporarily, to help with that) drinking recently and immediately regressed to my early bird habits, which I have had from childhood, and involve waking up pre-dawn. (It&#x27;s 5:30AM now, and I&#x27;ve been waking up at 4AM for a week.) Personally I enjoy both rhythms, and vacillate between them as it suits. There is no doubt in my mind that &#x27;early bird&#x27; is healthier for me personally, though.
