"i switched to opana er this year as the morphine er i had been forced to take since last summer made me very nauseated (even w/nausea meds), caused terrible headaches and didn&#039;t cover my pain adequately so i could live some sort of life. 

i have loved the opana er.  i take 40 mg twice a day and after the first month in which the switchover was difficult there have only been a few occasions where after i took the drug i started going through withdrawal.  i&#039;m not sure what was wrong with the pills as i set an alarm to take them and confirmed i took them. 

now am in donut hole. endo pharm won&#039;t help because there is a generic which costs more than the opana.  don&#039;t know what to do."
