Obstructive sleep apnea
Sleep apnea. That you have also sensed “small amounts of saliva/fluid clogging” your windpipe, brings two other considerations to mind, possibly but not necessarily related to your inability to breathe in or out and those are: 1) acid
refluxGastroesophageal reflux disease
Gastroesophageal reflux in infants
Hiatal hernia repair
Reflux nephropathy
Vesicoureteral reflux, also called gastric reflux or gastroesophageal reflux disorder (GERD) or, 2) post-nasal drip. The first of these is not uncommonly associated with sleep apnea. Finally, there are any number of functional or anatomic abnormalities of the larynx and vocal cords that could foster obstruction to air flow.
The latter must be ruled out, first, and this would best be accomplished by direct examination of your larynx and cords, via the use of a fiberoptic laryngoscope, by an experienced examiner, either an ENT specialist or a pulmonary disease specialist (Pulmonologist). If that is normal, you should proceed with a sleep study, despite your belief that you, “don’t think” you have sleep apnea.
Not being able to breathe can be very scary and I would not delay in seeking medical assistance for your problem.
Good luck
