thank you, im on the third day of my cycle, and i dont know if this is normal or if anyone has experienced this before, or maybe its just something else causing this, but since my first day ive had a really difficult time sleeping, i know its suppose to enhance sleep maybe its too early or maybe my system has to get used to it, but im having a hard time with the sleeping. i wont stay asleep for very long and then its very hard falling back to sleep, my body feels nervous in the night when im trying to sleep. i dont know if you understand what im describing , and maybe its because i have a chest cold. im just not comfortable at all when im sleeping and not getting a good rest. todays my third day so hopefully my body will adjust and i wont have to discontinue use, because im really excited about this stack. any advise is always appreciated... much respect
