"meh. i was on vyvanse, 70 mg/day &amp; switched to mydayis 25 mg/day. not what i was hoping for. not by a long shot. while it &quot;lasts longer&quot; than vyvanse (was on vyvanse for years) which only gave me about 5/6 hours in the end, it gives me much less motivation. makes me depressed. i&#039;m very sorry i did not only get only a 2 week supply rather than 1 month. i have no insurance &amp; it was about $100 more than vyvanse. needless to say, i will request vyvanse again at my next appt. big disappointment."
