So I will get try to keep this short and sweet.

For the past 15 years when I get stressed or anxious I start to gag horribly non stop and the only way I can control my gagging is with a mint or liquids. Now its not only just when I'm anxious...I also have it with the following

1. Lack of sleep / fatigue (If I don't get 8 hours or more of sleep its uncontrollable)
2. Caffeine : If I drink coffee it triggers my gag reflex
3. If I workout or excersise i immediately feel the gagging come on
4. After a meal and I'm full its REALLY bad

I feel like there might be some sort of neurological issue or underlying condition that is causing this but my question is if there is anyone out there who has had this symptom that has figured out a cure to it or a resolve? Cause I honestly wouldn't mind anxiety that much but this symptom spirals things out of control. 

I've been to an ENT who looked down my throat and found nothing so I really don't know what to do nemore cause I've tried anxiety medications and nothing fixed it. I had thought it was GERD at first but it's not so i'm just lost at this point. 

If anyone else is experiencing this or does let me know , how do you cope? is there anyone out there who figured out how to get rid of this? any ideas?
