Uncomfortable breathing when asleep. feel my lower throat is stronger, like breathing through straw. oximetry test was normal. make sleeping hard

Need to be evaluated: The problem is not your level of oxygen but your flow of air when you sleep. You might have Obstructive sleep apnea or diaphragmatic dysfunction. You should be evaluated by a pulmonologist .

A nighttime pulse ox: (desaturation) study is a reasonably good screening test for sleep apnea, but, like all screening tests, it has "holes" thru which some disorders can slip undetected. You might need a more complete sleep study. Keep in mind also that Klonopin (clonazepam) and its relatives are sedatives that, especially in combination with alcohol & many other drugs, can suppress breathing. Best wishes. Dr. Anne.
