Now my solution is not perfect, but when the weather is cooler/cold I tend to sleep better during the warmest time of the day (typically 2 pm - 6 or 7 pm). So I tend to get off schedule, and nap in the afternoons, but what can you do? I sleep better during the day when it's warmer, than at night. So my solution is black out shades for the day and satellite/cable tv for the night. (Or Netflix.)
