I have a question for the commuters out there. Up until about a month ago I biked to work a few days a week. I have been doing it for two years now and love every minute of it. Lately, however I have had trouble sleeping. As my commute is 14 miles each way, I have to go to sleep earlier when I bike than when I drive. I have found when I have to get up at 6am, falling asleep at 1:00am-1:30am doesn't cut it, so usually I fall back to sleep to grab the extra half hour and end up driving. I need to start biking again or I will go crazy sitting in a car every day. Has anyone else experienced this? Any advice on what to do?
