@zaa I haven't noticed my nose being very dry. Also have not heard of any issues with using a nasal rinse twice a day. The nasal spray has helped a lot for me but the little spray bottle leaves a lot to be desired (IMHO). It has a 2 inch plastic tube that is really not flexible attached to the top of the pump bottle and you have to hold the bottle at an angle to pump which is OK when the bottle is full. Now that I have less than half left in the bottle I have to mess with it because I can't bend the tube to keep the bottle upright when pumping the spray. It's definitely worth a try to avoid any kind of nasal surgery.
The NeilMed squeeze bottle does not have a tube. They are available at any drug counter. They also have med packets.
