Welcome!!
I think it's very noble that you have come to this decision on your own.
There are many tools on GYE which are built in order to help you, and others, keep their promises and aspiration of not doing these stuff again. Take a look around and see what speaks to you and what makes sense.
It is hard to restrain yourself from doing it when you think about it from purely a spiritual reward/punishment side (which you should). It might help to tip the scales to not do anything when you think about the repercussions the act will have on your life. Take a moment to think about what made you decide to quit, and realize that by giving in you are bringing upon yourself the bad things you wanted to get rid of. Just as a brief example: For me, i decided to change because it was rotting my brain and i couldn't think straight, i use that as a deterrent not to do it again, whenever i struggle i think back to what my mind was and my thoughts were at that time, and i realize my mind is much clearer now and im able to think better.
