Hello Rachie.

Are you taking any antifungals? I recently started taking olive leaf extract in addition to the grapefruit seed extract I have been taking. While I am now experiencing a strong candida die off reaction(muscle ache) my head is so much clearer. I am also taking Molybdenum to help minimize the muscle ache. I am hoping the muscle ache will soon diminish.

As for caffeine, I am down to one cup of coffee a day now. It is very hard to give up coffee completely. I did it for a month a few years ago hoping that it would help me feel better. The headaches went away after a few days, but my craving for coffee stayed strong, and I started drinking it again.
