Safe home remedy to treat possible RI in ball python? Is it too late?

[tomjones456]

Not suggesting or trying to debate the issue . But I've had success with f10 .

If she's had RI for a year or maybe even two, is it too late to treat? But if she is willing to eat, is that a good sign that she doesn't have RI? The only thing is that she's had tons of mucus in her mouth and wheezes ever so often. It's been very hard to keep humidity high in the glass tank.. that may have triggered this.
