I can't do any of them... I think if I put the story on here you all would laugh, but it might be a real world connection if anyone ever crossed this, so let's just say when I was very young there was a traumatic event with bananas. Childhood trauma does surprising things to the psyche, and it definitely has a long lasting effect. (Not trauma as in abuse, but just a significant event type thing)
Don’t throw out your undewear when you’re in a binge cycle.
Do this instead: Grab a garbage bag, and put all your underwear in it, then seal it up, and place it somewhere in your home where the bag is hidden and out of the way. Try going 24/7, and see if you end up comfortable in that lifestyle change. If you find you’re going back into a purge cycle, you replace your underwear in that bag with your nappies.
An alternative is to downgrade from nappies to pullups when you’re feeling a purge happening. This may satiate the emotions enough to give you a half-way reprieve, but still allow you the decision to wear underwear from time to time, and pullups mostly, and then nappies when the binge hits.
I used to binge/purge too, throwing away unused nappies. The break from that for me was realising one day that I could just put my nappies away in a hiding spot. When I inevitably decided (after some medical issues arose) to go 24/7, I did the trick of bagging up all my underwear and hiding the bag.
