I got my Tranquilogen yesterday. Dosed I cap post workout and 1 cap 1h before going to bed. Felt somewhat more relaxed after my training session but the second dose taken before bed made me struggle to get some sleep. I felt alert and focused and ended up taking an ambien before I could get some sleep 
I think I will avoid Tranquilogen during the evenings and stick with a morning/mid day dosing. I also felt som pain relief in my lower back which was a good thing.
