Yes, I agree now that I think about it. Those of us that I have been in contact with that have TCS seem to have 'extra' mucus buildup. It is definitely aggravated by milk and cheese products, etc...
I also found that when I used antihistamines, or steroid nasal sprays, they would dry her up and then she sleeps much quieter. She seems to have outgrown much of the noise, somewhat (6 yrs old).
