Once you make a Big Plan, you will notice how unauthentic it feels when you think about using in the present (or future) tense. Of course, that’s your AV. It will suddenly become very correct for your reflective thoughts and feelings about YOU USING to all be in the past tense.
“...when I use cocaine...” instantly becomes “...when I used to use cocaine...”
If using the past tense feels unauthentic, well, guess who that is?
