pain
"This works well for me IF I take it with aspirin and tylenol. By itself, it does little - it would not be worth getting.  It also helps with sinus and/or migraines, again, only coupling it with aspirin and tylenol.  I have never had any of the "interesting" side effects that people describe, nor addiction.  I use it when I need it.  I can't help but think that the "druggies" (as someone else put it - pretty good descriptor) just THINK this stuff acts like a narcotic, and voila, placebo effect.  I just had to get a newly state mandated drug screen for this med.  I was squeaky clean, but also got a bill for $911 from the lab for the screen.  Thanks, druggies, for making it exceedingly difficult & expensive for those of us who are legitimate."
