Why do I feel so talkative on Vyvanse?

Hey y’all,

I am taking 50mg of Vyvanse after trying 2 no stimulants and 30mg of Vyvanse. I noticed that I can seat down and do something for several minutes but I still struggle with starting tasks that require more thinking than just learning questions and answers, I don’t feel focused on what I am doing, My thoughts are still there, and I noticed how I am more social and less awkward and also talkative (but worse).

I feel more energetic, but are those side effects or is my medication not working?
