I have been taking 30mg of Vyvanse for almost 9 years to manage my ADD. I am now a graduate student and need to focus for more hours in a day. My doctor suggested Mydayis. I am doing my research prior to switching and I am concerned with some of the side effects people have mentioned with the switch. I already have issues with teeth grinding, sweating, difficulty falling asleep, severe morning grogginess, and unrelated migraines. I am worried about the irritability, depression, and anxiety people experienced with the switch. What can anyone tell me about making the switch, pros/cons? Thank you in advance!
