at around 9:10 am i took 2 60mg vyvanses. About 30 minutes later at 9:40 i started to get nauseas and trew up several times about 5 mins later. Ive taken vyvanse at this dose before and not had problems like this. Its now 10:25 am about an hour and 15 mins after takin it and im starting to feel some effects despite vomiting. Ive neve heard of any1 vomiting that soon after taking vyvanse.
