I asked Giovanni that very question this morning, not knowing you had asked it, a question I had wondered for a while. He basically said in a Zen way,"it is to much when it becomes an obsession". He referred me to Eckhart Tolle's book "A New Earth" as a way of finding moderation. For about two months I did Kambo once a week, and it certainly became an obsession.
I have read how in Brazil the indigenous people got offended because the people in the city were apparently over using Kambo. Gio said that there is no set amount for Kambo. But for me once a month seems appropriate and a way to tamper down my enthusiasm to a manageable level of smooth conduct.
Your dots are sufficient given your experience I would say. I know you are a warrior and living up to your name. Some how I remember you from both the eboka forum and the nexus, I know you are on the right path of respect for the medicine. I would say that to me this medicine is holy, sacred and above all one of the most precious gifts on earth. As long as the respect is in tact in your heart and soul your spirit will respond in kind.
Lately I have younger people in their younger 20's very much wanting to do Kambo, but for now I deny them because I feel their enthusiasm is largely based in curiosity rather than legitimate respect for a sacred essence of healing.
Putting them off and being evasive will allow them to see that this is to be regarded with the highest respect above silver and gold. As someone that purged crude oil for an hour straight I have now a newfound genuine respect for Kambo. What it took out of me there is no scientific explanation and a new found energy I have found is simply a beaming fire gifted by the Frog God. Like a tank that never goes empty.
So as long as you put that respect deep into your valves of intuition every time Kambo will reward you. You will know you have been rewarded by how frog faced you get, how close you come to knocking at death's door, and what precious sentence it has to tell you. If it is easy and breezy than you are doing it too much. IMO. Unless you have become experienced at microdosing.
I have a very different technique than our elders of Kambo. Mine is to make the experience as intense and grueling as possible. When I learn the Meridians better I hope to adapt to the wisdom my teachers have to offer. But for now the indigenous panorama looms larger like an umbrella over a hallo. The crucifix of Kambo should twist and turn your every being and squeeze all the trash out. Then it is proper.
It can last from 15 minutes to 2 hours. My longest was 2 hours. If it is not as intense than up the dosage the next time. Always pushing further with bravery and love for what the Kambo has to teach your deepest being of sacrifice.
