I've been taking it for a week now. I work 7am to 5pm. I started taking it at night (9pm) and noticed I was becoming very tired by noon, but sleeping at night better then ever. I don't even wake during the night which is great. Can anyone tell me what times they take it and why. Is the morning best? I only started it at night because I read it may avoid the tiredness during the day. Has this side effect gone away for anyone? Thanks!
