Ah interesting. You sir or or madame unfortunately have the genetic predisposition to become addicted to opiates. Be very very careful.  You should not take them at all. I have been given opiates several times for acute pain and hate them, and would like nothing more than to be off them as quickly as possible. They produce no euphoria in me. They dull the pain very little for me, make me nauseous, dizzy and sleepy. Different genetic response. I could take opiates and would never want more. I prefer anything to them. Hospitals could easily test for those who are likely to become addicted with a few simple questions. And they should.
