"i am 18, and alongside my add, i suffer from major depression disorder, objective defiant disorder, and major case anxiety. after an emotional breakdown on a school trip, my doctor started me back on my zoloft and once i got that stabilized he started me on vyvanse. we started at 40 and that worked while i was taking my zoloft at night, but when i moved it to the morning, we had to up the dose to 60mg. i have experienced nausea, dizziness, increasing perspiration, and a little insomnia, but they don&#039;t last too long. i have also been struggling with weight pretty much my whole life. i started on may 2nd and i have lost a little over 20lbs."
