Hi, i took 70mg of vyvanse and literally felt no effect. i waited three hours. then took a 40mg vyvanse and still felt no effect. no help with adhd symptoms at all. i got this from king soopers. i was prescribed 60mg vyvanse 6 months prior to this and it worked. i got it from walgreens. the only reason i stopped was because it gave me anxiety. but the anxiety is being treated with zoloft. and the bipolar is being treated with zepraxa. and trazadone for razing thoughts at night. i was blowen away to find that it did not work. why would this be?
