Wow it's so great I found this thread. I started having the problem of the unsatisfying deep breaths and yawning/sneezing problems when I was a freshman in HS. Now I am 25 years old just recently having the problem surface again but now it seems worst, naturally. I too suffer from a history of anxiety issues. I'm actually tapered off of Klonopin (benzodiazephine) which I took for a couple years (mistake) and I heard that this is part of the withdrawal syndrome. Nevertheless, stress/anxiety is certainly a factor in this, IMO. All the evidence on this thread points to it.
My problem is basically this (simular to others)
-Constantly doing "Check breathes" to see if I can breath in fully. Sometimes it works, sometimes it doesn't. The real scary part is when it goes on all day where the satisfying breathes becomes a rarity for the day.
-Problems with yawning and building up a sneeze.
-Broncodialators/Anti-Inflamatory inhalers = a no go on this.
-Normal breathing is fine. Just can't get the deep breath fully a lot of the time.
-Can run 2 miles in 15-20 minutes with little difficulty
-Scared to death of a more serious problem such as COPD/Emphazima
At age 25, COPD is definitely a rarity but it becomes real pretty quick with an issue like this. I was diagnosed with a touch of mild asthma (starting to have second thoughts though after reading this). Especially was frightening when inhalers didn't work as COPD is related to breathing problems that do not react to broncodialators.
Good to see this thread is still going on since 2005!! Amazing! You rarely see this. On even high-profile message boards. I'm glad I'm not alone in this, but hopefully this will subside on it's on because hell, the inhalers don't do squat.
By the way you will find that Benadryl brings great relief to this (especially since most of this is related to anxiety/stress and the anti-inflamatory in Benadryl will open you up too. I wouldn't recommend doing this every night though. Just keep it around as a reassurance tool since most inhalers do not work for this breathing disorder.
I also would highly advise NOT to explore the benzodiazephine option (Xanax, Ativan, Klonopin, Valium). As good as this stuff is for anxiety/hypochondria, it will NOT help in the long hall and will shoot out triple the pain when it's time to get off if you get dependent on them. And TRUST ME....your odds of forming a dependency for benzos are 10 to 1. There are too many problems with benzo usage surpassing a month and usually does more harm than good.
PS- I do smoke!
