[My aunt --broke both hips-- back and neck and jaw in car accident --she has been on it for 10 yrs ---and calls-- it her life saving miracle drug and it has been the only thing that works. No bad side effects you want to drink alot of water on it. They tried to change her meds once and took her off she said the withdraw was most horrible exp in her life----they put her back on. Its cheapier then most opiates --the effects are long lasting 24-hrs or longer with one dose.
