I'm leaving the house, I grab the purse. It cut down multiple-times-a-week adhd-fueled returns home to one a month. Has this cured my ADHD? No! Has it made literally every day of my life easier and more manageable because I'm not stressed about forgetting something, or making my partner late to work? Absolutely!
Many of my ADHD friends still struggle with this, and I even on occasion will let a few dishes stack up on my desk while working for long bouts of time.
A lot of ADHD issues stem around the delayed reward system getting screwed up, and the best antidote for this is extreme proactiveness, doing everything immediately. It's too easy to wake up, say "I'll brush my teeth in a few minutes" and then hyperfocus for 16 hours straight until you fall asleep.
ADHD is its own worst enemy and building coping mechanisms or changing habits can be incredibly difficult when the nature of the disorder involves difficulty with sticking to new routines. This can be compounded heavily if there is comorbidity with OCD, PTSD, etc.
Can confirm. This is an extremely good way of putting it.
