Summary
The user took nattokinase, had a weird adrenaline response, then felt way better for a few days before entering PEM after walking a lot. They had been slowly increasing the nattokinase dose and were unsure whether to continue. In a later post they said they used oxaloacetate as needed but got a spike of horrible anxiety the next day or at night when withdrawing.
