I like to try one herb at a time to see the effects it has on me. I start small, as I can always go larger later. Maybe there is one herb in that mix that is a problem for you. Maybe you just took too much for you. That is the nice thing about powders, tinctures, and even weighing herbs. You can experiment with different doses. I usually experiment on a Friday so if I feel out of sorts I have the whole weekend to recover.
