"i have been constantly on pain medication for 6 years due to a wreaked back. i was on hydrocodone 7.5 4x a day; and it work fine, but when you take the same meds no matter what it is over 6 years it doesn&#039;t work as well after a while. so i talked with my doctor and he dr. decided i needed to try  hysingla 20mg, and assured me it would work great. well after two weeks of sleepless nights and loss of work i had had it!! this was the biggest waste of my money and time. not only is this crap cost twice as much with my insurance, but it does not work! i understand why doctors would want to try it; for fear of opiate abuse, but this is causing more and more people who are truly in need pain!!!"
