Dolotin Vs Morphine, Which One Reduces The Pain, But Keeps

Dolotin vs Morphine, which one reduces the pain, but keeps you more lucid? I have a friend in Hospice with Cancer, and Morphine is being used, recently, I was in a serious motorcycle crash, and Dolotin via IV was used for my pain control until orals could be correctly adjusted.. it seemed as if I was fairly lucid on the dolotin.
