Hi, I have been taking Vyvanse for the past year. It generally makes me concentrate and feel happier. I took my first dose of 10 mg Prozac today, and I am not sure if it is the placebo affect but I feel somewhat less emotional already. I have read all the bad side effects Prozac may have on you and I am wondering if the Vyvanse might cancel out the "non-stop crying" & "anxiety". I also am going through a breakup right now and starting school again so I am under a lot of stress and dealing with a lot of feelings.
