Thanks MizKitty's Avatar. that artical was of great interest. Though a bit heavy on the technical. I got a good bit of info off it.
I am thinking that I might have a few insulin problems. As I have found when I cut carbs from my diet, I do not get tired like I used to.
Therefore, maybe my body does not handle the blood sugar levels as good as others might. This might be why I am not loosing weight with the St Johns Wort.

Thanks again.
