What if long term caffeine use causes some of the adhd symptoms? It interesting to ponder because if I stop using caffeine for a month, some of my adhd symtoms go away completely. I've done stints of complete caffeine breaks, content consumption breaks (one week or more without screens) and I felt amazing and alive. The first couple of days of using caffeine feels amazing but then I feel dead inside again and live like a robot. So in my mind, caffeine is my main target when I try to adjust my routine/behaviours.
