Nausea/Vomiting
"Started taking Promethazine at 25mg 3x daily  yrs ago then to 4x daily  for severe nauseous and vomiting from treatments for cancer and couldn&#039;t keep food down at all. I was also on strong pains before &amp; higher w/cancer Oxycodone 30mg 4x day &amp; Morphine 30mg ER twice daily for having 18 fracture vertebrae (8 herniated, 9 bulging had 1 ruptured disc repaired) an separate AC joint in right shoulder an other broken bones an left over bullet &amp; shrapnel fragment in both legs &amp; right foot due to 17yrs US Army 3 Combat tours.
I found that the Promethazine didn&#039;t always work well as it should&#039;ve at times I did go over an take couple more of them per day than what was prescribed. 
Didn&#039;t notice if it help w/pain meds. On them again cancer returned."
