I've never taken my health for granted. Even while trying to destroy it with alcohol, I've been mindful to be grateful for what I've still been able to do and appreciate because my health remained relatively good.
But I have to admit that after the way I've felt for the past several years, it does feel like a great weight has been lifted with the disappearance of those symptoms. I want to be careful about this, though. I don't want to say I was unhappy because of those symptoms, and that I'm happy now that they're gone.
I think I've been pretty happy for a while. The health issues were a bummer and reduced quality of life, but if asked, I don't think at any point I would say I was unhappy. And with the issues abated (mind you I don't know if this is temporary), I'm experiencing pleasure in being able to eat and in the motivation to get out more, but that doesn't mean I'm any "happier" than before.
Taking pleasure is different from happiness. If the symptoms come back, the pleasure will be gone and it'll be a bummer again, but from how I've defined my happiness, that shouldn't be affected. If my happiness depended on my pleasure, that would suck.
