pain
"Don't if you can help it. Yes a shot of this IV will STOP your pain, and possibly the rest of you, pretty much immediately. If you have a low BP or sensitivity, or have never taken a strong (Norco doesn't count) narcotic before, try something else first. SEVERELY addictive. One shot and you will want another one, no joke. ONE SHOT. The pill version by comparison is slow acting and hits for a long time, most people will find better relief with percocet. Unless you have just had surgery, been shot, or have a broken bone, try Fentanyl first, at least that won't kill you in one dose."
