I'm a 16 year old female and my neurologist (I have epilepsy so I have been seeing my neuro for the past 4 years: I take Lamictal for epilepsy) prescribed me Vyvanse couple of days ago because I told her that I can't concentrate in my classes and that I forget things easily. I was a straight A student until last year. This year I'm getting 70s in my classes and I'm not happy with it. I'm taking 30 mg of Vyvanse. I'm writing this on my second day on Vyvanse. My appetite went down , now I have to force myself to eat something and I have a dry mouth ..Are these side effects going to go away... I don't see any positive effects from this medicine. I still can't focus or concentrate in my classes..however I think I'm a little bit motivated..but that is not helping. What's the point of being motivated if you can't absorb what is being taught in class? So I want to know what you guys think :( Do you think It will start working once you increase the dose?
