I was not aware of how often I swallow air-saliva, until I tried to limit how often I do it.Only problem is now my mouth keeps filling up with saliva and i have to keep spitting it out.I read that the average person can swallow up to700ml, so surely most of this is unconsciencely swallowed.Anyway, happy new year to allhope 2007 brings medical advances and new insights into this frustrating condition.
