"my experience with the drug is somewhat unclear to me. i was diagnosed with adhd when i was 23, i&#039;m 24 now. in that time i have trialled a series of drugs. atomoxetine, methylphenidate and now vyvanse. out of the lot, i would say this one has probably been the best. however, as time progressed i felt the effects of the medication deteriorate which is sad and frustrating. it almost feels like it only ups my mood (not tackle symptoms). however, the first time i took it was amazing. my ability to concentrate was unbelieveable! i felt a strong sense of motivation/confidence in what i had produced. sadly this was limited and the positive effects began to deteriorate as time progressed. i will never forget the first period though, it was liberating"
