I don't think I'm going to carry around painkillers
Why don't you want to carry them around?
I don't want to help myself with medication because I might be going to have a trip out of my life.
It's dangerous to carry drugs on you so it makes sense that you might not want to keep them on you. If you don't feel safe carrying the drugs on you then you should leave them at home.
I do want to be safe.
Good idea, you should just leave all your medicine back at home. There's a time and place for everything, and holding onto it and being dependent would prevent you from enjoying life. I'm sure your family would be proud too, for not abusing meds.
