Vektor, I know exactly how you feel ... I have a similar issue with tachycardia and anxiety. I've been resisting a full-on investigation because I don't quite trust modern medicine yet -- while doctors are great at mending injuries, their ability to tackle disease
often seems hit-or-miss.
I don't want to speak for everyone here, but I bet they all share my hope that you continue "feeling pretty good" and keep finding the time to bang out amazing images to share with us.
