This is a good subject, but I would like to take a different view for a moment. So far everything mentioned so far is the BDSM side interacting health wise with the rest of your life. What about life's inevitable influence on the BDSM side.
As much as we may care for out sub, or sub caring for a Dom, there are going to be times when they become sick, hurt, or otherwise unwell. I know for me personally that when my sub is sick I do all that I can do help her recover, not just because i care for her, but because it is the thing to do. I will admit at times that I find it very hard to carry on in the Dom/sub relationship when she is ill.
Also, I think we will all agree that there are times that life takes precedents over the D/s relationship, say even over shadows it. This can be anything from someone in the relationships health to the health of another ailing loved one.
So, how far do you let an outside health issue take precedence over the relationship?
