I ended up with a kidney surgery when I was young from holding it. I ended up with hypoglycemia from forgetting to eat regularly, for extended periods during high school. My teeth also had a rough time with bad habits.
It is a wonder I was not diagnosed for adhd earlier (44 diagnosed 2 mo ago)!
Because of health issues now still stemming from those younger years, I am more vigilant about bathroom breaks and at least healthy snacking if not proper meals. I keep flosspicks around and handy. Though, I still may not shower until halfway through a day and a future task now requires it, and other small things. Like, I will be sitting and intent on something and feel my leg tingling and telling me it's falling asleep, I won't pay it any attention though to shift or wiggle. Instead, I'll get a cramp or, finally go to move and have no feeling in that limb and be stuck. That's when my brain will acknowledge that we knew the whole time and just ignored it.
Medicine has been very helpful, though there are still habits that need correction after so many years ingrained.
