HI, I'm new here- my disorder started around 12 yrs. of age. I can remember not being able to breathe during swim practice. Now at 30, I've finaly started looking into a possible disorder/treatment. I didn't realize this was not normal. I feel this way 1ce/2x a month to going weeks w/o one. They also effect me up til I can fall asleep, and resume as soon as I wake up. My therapist(of 3 months) is doing Eye movement desensitisation rehab. not sure if it's working, also started effexor- but right now having just as bad an attack as ever. Feels like someone sitting on my chest, I have a lump in my throat, I have to swallow hard, I take huge gulps of air-constantly yawning hard, sometimes til my lungs burn, and my face tingles. When I yawn, I need total concentration-no visual - sound distractions. I have to sit up in bed to breath. Everyone that knows me has seen this happen, at first thinking I'm tired or bored. If any of you have been succesfully treated- please respond. It has been so extremely aggravating- and I've just started researching. sorry for the long post- spelling errors- please respond with any info -thanks-Caroline
