"i am an 18 year old female with adhd and my doctor just switched me from vyvanse 30mg to taking focalin 10mg xr and i absolutely hate it. vyvanse worked for me but would make me bite my lip often in class which was very odd, but something i could work with...focalin makes me socially anxious (keep in mind i am the most social and extroverted girl), jittery, and worry about random things. i am going to doctor tomorrow after taking it for 2 days and going back to vyvanse."
