kitty, so sorry things are not improving from the last time you posted. The fact that she goes for long stretches at night is very puzzling to me as well because reflux is the first thought I would have. How and where do you feed her? In a quiet, dark room? Have you tried different people feeding her? Maybe she is just really touchy and gets easily distracted, picks up on your tension as well.
At least you have an appointment on Monday. The plugged nose could definately be a factor. Of course, such things really have to clear up on their own. I hope things get better. Keep us posted.
