We have very similar psychedelic histories. I agree with everything Tat said. Creating the spice in your life is a unique experience.
I have been thinking a lot about the fear thing and DMT. A part of me thinks that the fear is coming from the ego who is afraid of it's existence being blown to bits. Another way I look at it is that fear is part of the lesson. Letting go of fear and finding courage.
There is a way to change fear. Look at it. What is it? Excitement is a form of fear. Just before you get on a roller coaster you fill with excitement. The line moves slowly and you slowly approach the cars. You line up and soon enough it's your turn to get in. You chose the front this time. Your heart is pounding as the cars clink and clank up the steep incline. Slowly coming to the top and AHHHHHHHHHHHHH!!! Hands up and the fear is released into an unexplainable joy and exhilaration!
DMT is the same way if you look at it that way. If you have fearful apprehension so much that it is affecting your trips, making them difficult, then take a break until you can start to enjoy getting in line for the ride again.
"In the universe there is an immeasurable, indescribable force which shamans call intent, and absolutely everything that exists in the entire cosmos is attached to intent by a connecting link." ~Carlos Castaneda
