Hey Atlanta, yeah after complaints about fbo stopped I got complaints like homeless/musty/etc.
Don't be a wuss lol :P it hurts less after you do it a few times. I didn't know what I smelled like or how strong it was until I did the first flush that worked. I think your reaction of the smell getting stronger was the flush wearing off so you become more aware of the scent coming back. I was so offended by (even my urine smell!) the smells I just kept flushing. I do the sinus flush daily before work after shower. Maybe I should so just saline one at night too? Hmmm. Good luck. Keep trying, I think we are onto something.
