Just another little thing that may be helpfull on your list. Write down things such as: the craving, how bad it is, will pass by. When you feel you are about to use, and there is a possibility: get out, walk away from that situation. Go for a walk, stay home and put on your favorite music. Keep in mind how proud you will be afterwards.
It's not so hard not to use when everything is going well and you have no craving. The real work starts at these hard moments.
Wish you strength!
