It does read a little bit like astroturfing, but as someone who had a (different) lifelong debilitating condition that has been almost entirely solved by a few doctor's appointments, I can say that nothing turns you into an advocate for something faster than this sort of experience. For me it was almost spiritual in the end. It was also oddly upsetting in some way, thinking about all the years I had wasted when essentially two hour-long appointments were all I needed. You gain this almost overwhelming need to help other people avoid the same morass you were in.
