It just comes running out the other side. I'm adept at one side and challenged with the other. It's kind of like swimming and breathing.

I love it! I've noticed that my nose is running more than before but I think that's my sinuses clearing themselves out. I haven't been good about doing it every night but I should start being more diligent.

I've noticed the headaches are gone, borderline sinus infections never manifest, and I have not had a cold since I started. I've also had more energy and waking up is SO much easier.

I know that this could be in our minds but I think it isn't. The first time I used it (and sorry to be gross here), I didn't have a full-blown sinus infection or anything. I felt better than usual, actually. After using it, I blew my nose and all these little yellow dried bits came out. I think it's pretty cool to be flushing that stuff out.
