I was wondering how long it takes your daugther to nebulize the 7% hypertonic saline? It takes around 20-25 mins and I am wondering if that is the usual time. We do inhaled GSH in the HS and we buy it from theranaturals.com. It's called GSH Plus and is $35 for a bottle. We do it twice a day. We also use Tobi and it does not seem to be a problem so far. Best of luck.
