Fwiw: I worked for an insurance company for over 5 years, ran an alternative health site for a number of years which is being discontinued, and have participated in various health sites over the years. I really hope you have success with this. I just know it to be a tough space.
Peace.
PS I will add that it also goes over well on HN to upvote people if you appreciate the reply. That seems to frequently get overlooked, though I try to do it.
