In some it causes nausea. You don't like it, fine. But I don't understand how people can be so pro marijuana on one hand, and so anti-opiates on the other. It's pain. It's not noble to suffer needlessly.
It's complete BS that it's harder for a dentist to prescribe a dozen Vicodin after a root canal these days. Or that many doctors will try to pass off 800mg of ibuprofen as a substitute for Vicodin for throwing you back out. That turns a couple of days of "be careful and taken it easy" into a couple of days of laying around on the couch in pain instead.
These drugs are inexpensive, very effective for short term pain management, and the vast majority of people have mild to no side effects, and almost no one has an addiction issue from using them.
It feels like the modern equivalent of Reefer Madness.
