For the last few weeks I've had the same issues as you, Kitty... I can't seem to sleep when I'm in the midst of a spell of fatigue, but then I get this second wind of energy just around the time when I "need" to sleep. Unfortunately because I have two young kids at home and set work hours I can't sleep when I want to. I found a half tab of Unisom in my cabinet yesterday from my days of pregnancy nausea and took it, that was great. I wonder if LDN will help with my sleep issues or just keep me awake if I get up during the endorphin rush period?
