Does she have a heat pad? I don't know, but if it's not producing frequent stools she may be having problems digesting, and that could be from not enough belly heat.
Anyway, I live in Miami and the humidity this time of year averages at between 85-90%. There have been a few days where the humidity drops down to 60%, but it's not common and there have been days where it goes up to 99-100%. The humidity inside, with the AC on, is not much different... but by being able to control certain things, I'm able to lower humidity in my leo tanks to between 40-60%. A heat pad helps, because it's dry heat. I use a fine sand for one tank and dry paper towels for my other tank. I keep hygrometers in there (cheap) to know the humidities and place them wisely, where there is good air flow.
The difference between my frog tanks, which vary from 70% to 90% humidity and my leo tanks is huge. There are ways to get around it!
