I would consider trying another medication or at least lowering dosage. If you’re lucky enough to live in a country that has doctors who (like Dr. Jain) are well educated about the drugs that can help ADD and ADHD symptoms you should definitely make sure to get an in depth talk with one.
Luck luck ahead!
