Butterball, I felt more energetic after about 2 days. It just seemed like I started doing more (walking futher, starting projects instead of procrastinating) & feeling happier about it. I felt the Relacore helped with my stress level because I can be a little on the anxious side at work when I'm short-handed (especially during a holiday weekend), I just found myself being more prepared & calm. So I guess I'm just trying to tell you that the energy, mood improvement, & reduction of anxiety was kind of subtle, but noticable at the same time.
