I have kids. Like the previous poster, they're too young to understand. I plan to tell them as they get older. We are also pretty open with our kids when it comes to health issues.

I think the impact on them has been as minimal as can be hoped for. The major factor in this is that my wife is normal and is solid as a rock when it comes to taking care of them and planning activities outside the home. Because of her, I'm able to get out more than I would otherwise. There are times when I need more sleep than the rest of the household, but I do what I need and go to bed earlier, take a nap, or whatever. My BP is well-controlled with meds, and hopefully I'm giving my kids the most normal growing-up experience possible.
