IBD? RI? Or just paranoid? Help!

[Skiploder]

I've seen her start to stargaze (she'll stick her head straight up for about 2 or 3 minutes at a time but never doubling back)

That's not star-gazing. It's either because of her respiratory infection or some snakes just do this. Maybe they see something interesting overhead, who knows, but I have a few who do it and have been doing it for years.

Bottom line is that she's eating and putting on weight. That's an excellent sign.

and after a 3 weeks of good health, she's open mouth breathing, popping, and wheezing again. I've done a few tests that I've read (laying her upside down and she does right herself imidiately as well as holding her from her tail and she doubles back and climbs back up to my hand). She is eating like clockwork, and doing her business just fine.

IBD? - Do the signs of IBD ever seem to fade then return? Or is it normally a constant downhill of health?

It sounds like the original case of RI was never really dealt with. Get her properly treated via your vet and get her clear of the RI.

If she continues to get RIs after being properly treated, and still is experiencing stomatitis (also after being properly treated), then you can start to think about more serious issues.

IBD does not fade and return. It presents itself as a serious of ailments that stem from the compromising of the immune system (think AIDS). Infected symptomatic animals can show a wide range of symptoms, from neurological issues to chronic infections that clear, then come back.

Again - you first have to make sure that your snake has been properly treated per the instructions of your vet.

RI? - Any way I can help this without taking her to the vet? I wish I could take her, but I currently do not have the funds. Should I continue to administer the oral mouth cleanser, or is that going to cause more problems with her breathing?

If this is a possible case of mouth rot, I still have that oral cleaner, I've been giving it to her daily, but I'm not seeing any improvement.

She needs to go to the vet. A lot of people will give you conflicting advice on home treatments for the various symptoms she's having, but in the end, your Vet needs to diagnose her and administer the appropriate treatments.

Ditto on the stomatitis. Can you still see the infection? Did you administer the medication for the full duration? A follow up appointment with the Vet is your best course of action.
