I am sort of the opposite. I can easily sleep and nap on rest days. I attend a 4PM 3 hour training session at the track. When I am finished at 7PM, I have to drive back home, get cleaned up, eat dinner and then try to fall asleep and stay asleep. My sympathetic nervous system is so jacked up from the HIIT, it is harder to fall asleep. After I get ready for bed, I read. I find that reading relaxes me. I have the same peeing at night issue that most have. So it goes. The green laser is beckoning.
