I am with you, Norah, I would not take tablets - but then at a family gathering I discovered my cousin's son, a hospital consultant, has been diagnosed with ADHD, and he has the tablets, but only takes them when he needs them. They are there if needed.
Like you I have developed strategies for dealing with my problems, but having talked to DS recently, who is close to having a breakdown because of his ADHD, ADHD presents itself in different people in different ways and I can see that my strategies. He is also a senior academic, involved in lots of projects, having to take on more and more administration work, and everyone in the department, neurally diverse or not, is under strain because of the number of balls they are juggling and generally the neural diverse among them are struggling more than the thers.
I think you were also fortunate that those around you, teachers and parents, understood your problems. For most of us, and I am your age, nothing was known about these problems and even with loving, caring and worried parents, I was generally seen as a rather odd child who was just not trying hard enough and far to careless.
