"biggest waste of money. don&#039;t believe all the lies put out by drug co. very unpredictable in its delivery. pain comes in spurts for me so something that won&#039;t do me any good for 5 hours is practically worthless to me. if i have to suffer that long for relief then i might as well not taken anything. i understand that&#039;s it&#039;s not designed for breakthrough pain but still need more predictability in a pills delivery to judge how to take it. i have very bad stomach issues as well."
