I get a stronger headache when I end up on the auto pilot of the margo memories then I do on the auto pilot of the Ann memories. Ive been told its because its a bigger jump for my bodys chemicals to switch to rerunning the body chemicals of the memories from when I was 10 then from my present age 43, then it is to switch to those of the Ann memories of age 30. in one situation my brain is switching my body vitals and chemicals down the equivelent of 33 years (43 down to 10 year old memory content) and in the other I am physically vitals and reactions are going down 13 years (43 down to 30). so yea you're right on with your theory.
