Dosage question

I am 64 years old.

A regular md diagnosed me with CFC several years ago. I have improved greatly over the years and he felt that perhaps the illness had "burned itself out of my body". I no longer have the constant sore throat etc - I was able to return to work full time - chemicals do not bother me as much as before and I have a fairly normal lifestyle.

However I still have what I call 'brain fog' where its difficult for me to concentrate..I am always tired no matter how much sleep I get and have little motivation. I exercise regularly and careful about my diet but still feel 'drained' all the time.

I recently read an article from the British Homeopathy Association which described similar symptoms and the remedy. I also used your remedy software and found that Lycopodium Clav could possibly help. So the dosage advised by the BHA was Lycopodium clavatum as a 12c potency to be taken twice daily for five days out of every fortnight.

I ordered and received the liquid form from your website but confused as to how to take it. Is one drop of the liquid 12C or would it be the 4 drops that is listed on the bottle?

Thank for responding and for helping me.
