What are you talking about in your comment? I disagree, Opioids simply mask pain, and some euphoria is one of the benefits in this regard. If you take an opioid pain med, then, (some) euphoria will exist until the dosage is no longer effective. However, if an opioid is used correctly, and by this I mean the patient is really suffering from pain, and the patient’s / medical professionals desire is to maximize the opioid’s effectiveness, then, less is more is the correct approach. Increasing the dosage too early can have the opposite to its intended effect rendering it useless.
