question: Our mentally challenged daughter (age 45) has been having dry heaves intermittently over the past 14 hours.  Gravol was taken 6 hours ago (every 8 hr.)  She is not verbal and complains very little unless pain is substantial.  Past episodes of 2 - 3 hours of apparent discomfort, occurring 2 - 3 times annually. X-rays via our family doctor and consultation with a Proctologist have not rectified the problem.  When complaints are made, her hand motion is on her right side approximate to the liver.  This occurance, complaint of pain during these dry heaves is from the front of her stomach.  If the heaving continues another few hours, a hospital visit will result.  Any input is welcomed.
