When i go to sleep, within minutes i wake up coughing/gagging. it also feels like i have stuff in my throat, and need to swallow in order to breathe. i used to get it once a month, and now it happens every time i sleep. could this be sleep apnea or asthma

Sleep disturbances: Phlegm in the back of the throat that occurs during sleep can be caused by post nasal drip or acid reflux, and may be related to sleep apnea. A sleep study would be helpful to sort this out.

Yes, post-nasal drip: GI reflux etc. Given description, mucous would ↑ any sleep apnea issues with tongue falling back into pharynx enough to close airway or asthma. Internalized grief/revulsion could drive the secretions, issues most Docs ignore. Trail Prilosec, etc? Sleep on side/prone, avoid back to minimize sleep apnea. Get a home, 3 night or more, sleep study for clues that you are closing off airway after asleep.

Cough: Your cough may be due to post nasal drip. Use saline nose drops or an antihistamine like claritin before bedtime. Use a vaporizer and sleep with several pillows or your head in an elevated position

See Dr. ASAP: I would get to a Dr. asap to give them a history and let them exam and run tests. Hard to determine any type of source from your many symptoms. I would do this soon.

Yes, asthma is a: possibility as well as acid reflux, post nasal drip, anxiety/panic attack etc. Get examined. God Bless you!

Also could be GERD: Nocturnal awakening with cough and post-nasal drip should be reviewed at a medical visit. GERD, asthma, sinusitis, and sleep apnea are all possibilities that can be serious issues affecting respiration. Tests, physical exam and a thorough history are indicated.
