My heart goes out to you with painful periods/PMS. I am well into or even past menopause. Don't miss my fertility one little bit. I have a sponsee who has horrendous periods and yet she stays sober and abstinent.
I use the phrase 'this too shall pass' with all kinds of situations. Whatever angst I'm feeling, be they heavy emotions or physical pain, I tell myself that it will pass. If I drink or eat over it, then I have even more problems.
Also, my most precious possession, my relationship with God, will be gravely affected if I give in to any of my addictions.
Wishing all a pleasant and abstinent weekend.
