Holding grudges is a form of self harm.

I respect your personal experience.

We can probably do this exercise with most drugs/psychoactives. No matter what you use, our bodies are designed to find homeostasis, so we will always get used to whatever we use regularly. Although we can use almost all of these things for a little while without doing too much (permanent) damage, it is always better to try and find a way to live without them. Unless prescribed by a good doctor to treat a condition that is worse than the side effects, of course.
