Welp, here I am, joining the club. I've been suffering from this off and on for 15 yrs. At first I related this to possibly an eating disorder. I was so scared of gaining weight and I love to eat! Everytime I would eat what felt like a little too much, the breathing thing would kick in-or should I say, the "lack of breathing thing". I am not overweight either and really don't have a problem with gaining weight, even at 41 bit I do think about it constantly. Everytime I mentioned this "yawning" thing to a Dr., they would look at me with a blank stare. I notice my lack of air mainly when I lay down. I sit down to relax at night, and as soon as I get horizontal on the couch watchin my favorite show, (thinkin that i'm completely relaxed) here it comes. No one else has mentioned the watery eyes that come along with it and the runny nose and how you get all stuffed up in the nasal passages. The watery eyes are what bugs me the most. I know that i'm not going to die from lack of oxygen and I don't really worry about that or panic about it. It is almost like having a tick (spelling). I do suffer from allergies, but never thought it was very bad. Most of my allergies are a 2-3 on a 1-5 scale. I had assumed that it was related to anxiety but what the heck to do but go on medication. I have nothing against meds if you need them but like others have said before, "i don't feel stressed". Meds would be a last resort for me. I also suffer from ulcers inside the mouth and have always related those to stress. I went thru a period in my 30's (which now I can look back and see much stress) when I was suffering from either the yawning attacks, acne, or mouth ulcers. But don't remember ever having all at the same time (thank god!). I am a pretty mellow person all in all, very patient and don't have much to worry about in life. I am a married, stay at home mom of two little well behaved boys, but hey, like I said before, you don't think you are stressed, but your body tells ya different. This (my diagnosis) is just how my body deals with stress. I'm sure that doesn't help anyone, but once again, it helps to know there are others out there. Like chocabloc said, it is comforting in a wrong way! You don't wish it on anyone, but it is such a comfort knowing i'm not alone.
