I’m so sorry. Usually if you are taking meds for a purpose, dependence is the last thing your body and mind develop. Your body—pain receptors—are fulfilling the purpose for which they were designed—survival.
If you take opioids and you are not in pain or at doses which are not required to control the pain, your pain receptors are not being used to fight the pain at hand. They are being flooded with unused drug.
What happens when this occurs? Euphoria. Relaxation. Peace.
These side effects don’t appear “bad” to those seeking pain relief. But when coupled with tremors, fatigue, constipation, gum inflammation, and dependence.
However, when treating severe pain with opioids, euphoria should not occur. That is your dosage gauge. If it occurs, lower the dose. Increase the dosage if the pain is greater than an 7 or 8/10 all day, watch for euphoria though and do not increase too much.
Euphoria will send you down the road toward dependence faster than any other side effect of the class.

They should be used only as a last resort and then only with caution, at the lowest possible dosage, and absolutely as directed under strict guidance and control of a pain specialist.
