I feel that Kambo will be the best option especially if done on the governer's vessel meridians. Ones on the spine are good, but careful with those as they are ultra potent in the nervous system, will need less dots. I feel that Kambo will open you up and then either Ayahuasca (brewed using Muricata as your vine) or Iboga (have you tried microdosing 30 days in a row yet?) will do the trick.
Again, if Kambo cured my migraines (temples) I really feel it can heal your third eye. Have you tried flexing your third eye? If you need I can send over pictures via e-mail of how to do it. Over time it makes the third eye stronger, I didn't learn about it from anywhere, it was something that happened naturally one time when I did Kambo and had had 2 grams of Iboga 2 hours before. It just happened and ever since I keep practicing.
I would need your e-mail pm'd to me if you want me to do so, or I have the lists here and if I had your permission I will end you some photos.
Blessings
