Diagnosed at 25, started Vyvanse right away. My ADHD is similar to what you describe, and the medication has helped with the mandatory chores of day to day life. If anything it has the effect of feeling that nothing is “too hard” for me and that I am not “too dumb to learn or do X”.
Side effects are light to moderately sever headache if I don’t drink enough water, IBM, high blood pressure and a pinch of insomnia.
It’s all worth it.
