Morphine (Kadian, MS Contin)
Painkiller named after Morpheus, the Greek God of dreams.
Morphine is highly addictive. Tolerance (the need for higher and higher doses to maintain the same effect) and physical and psychological dependence develop quickly. Withdrawal from morphine causes nausea, tearing, yawning, chills, and sweating lasting up to three days.
