Playing with sympathetic and parasympathetic can be hard. Many times people are making autoantibodies to both sides. There is some science that those antibodies are blocking the chemicals from getting to the receptor like they need to be.
Ansar testing (Ansar is controversial) tells me I am parasympathetic dominant. Digestively I agree, I have rapid gastric emptying and fast total transit time. But, on the flip side I get heart rate increase upon standing and some slight blood pooling if I stand in one spot for too long. I really want to do the cell trend test.
