I tried 1 capsule yesterday for the first time because I had read so many good things about it. I had a horrible night. I woke up after only 2 hours of sleep feeling very anxious and wired. I was up most of the night after that. Thankfully my DH stayed up with me and made sure I was ok until it seemed to wear off around 5 am. It seemed to have an opposite effect on me...has anyone else had this happen to them?
