What do you study? http://cmfcarnesnobres.com.br/buy-sporanox-baikal-pharmacy-bkqx sporanox 3d generico Thanks for being in touch and my sympathies for these frightening episodes you describe. The most likely cause is acid reflux where acid from the stomach refluxes up into the throat at night and tips over into the larynx causing it to go into spasm. There is a useful article available on the internet that explains this more fully - R Thurnheer ‘Sleep related laryngospasm’ European Respiratory Journal 1997, vol 10 , pp 2084 -6 . This can be prevented by taking the acid suppressant drug Omeprazole at night. There are several other possible causes including post nasal drip associated with an infection of the sinuses (see my response to Shirley D below) and ‘sleep apnoea’. I’m sure you should discuss this further with your doctor.
