I wish that worked for me. I’d love to have someone give me a BS miracle drug sugar pill and actually be able to believe them. Even subconsciously. But subconsciously, I automatically disbelieve miracle claims (and even most efficacy claims) until looking at the clinical trial data.
Years of chronic pain and gobs of different meds to control it, most entirely ineffective but with side effects, does things to a person already inclined toward doubt. I’m also prone to nocibo responses, like the guy in the comic, but I think it’s sensations that are always there, I’m just being asked not to ignore the state of my body like I usually do, so I actually notice them.
