@johnbishop - the deviated septum surgery I had in 1997 did help my breathing. I don't have sleep apnea, so can't speak to that aspect. The first couple nights post-surgery were a bit ugly with trying to get the pain managed and sleeping with all the packing and in an armchair (they wanted me more upright for a couple nights). It was worthwhile in my case, however. My allergist was the one who referred me for the surgery, as my allergies already challenged normal breathing for me.
