I think I broke my circadian rhythm. I'm now waking up before the sun even comes up. How to reset it?
Bright lights. Try a checklist of activities aimed to help you received bright lights during the daytime until 2 hrs prior to go to bed: open blinds during daytime, buy a therapeutic bright light box to expose your eyes to at least for 30 min/day. Avoid caffeine containing beverages and food after 2 P.M. Darken your room as much as possible. No computers, tv sets, or digital alarm clocks in your bedroom.
