you know, I did feel better the next day. I guess it was simply my body getting used to things. I must say that overall I do feel better and the afternoon energy lag that I used to have is all but gone. I also don't feel like I need sugar anymore. I even went to an event where they had cake and people ate in front of me and I really had no urge to go get some. And as an added bonus I've lost a few pounds. So overall I can say I'm pleased. Life is good!
