so, I've been on Concerta(methylphenidate) since I was at least 6 or 7 and I stopped taking it in high school. I was on another medication for a few years after quitting concerta but it made me tick like I had tourettes syndrome and Idk why. when I started smoking marijuana I felt so much better but grew a tolerance to it to the point where it doesn't do anything. I've been having more difficulties with concentration and I'm getting easily distracted again. who has tips for focusing better without harsh medications or expensive therapy? TIA 😊
