I had three abdominal surgeries in 2 years. They prescribed me painkillers after each one. I took one when I got home after the first surgery, and decided I didn’t like the way they made me feel. I didn’t enjoy feeling groggy and drugged. Threw the bottle away, and never used any of the scripts they gave me after the other two surgeries. How people can take those on a regular basis and feel good is beyond me.
Some people it makes them sick. Some people don’t like the feeling. Some people (too many) LOVE the feel and can’t get enough of it. Don’t feel superior because your system is different or you had a better upbringing. You’re still human.
