"i have been slowly taking increasing doses of vyvanse for recently diagnosed add.  i&#039;ve been on this particular stimulant for probably 6 months.  i was increased from 50 to 60mg a week ago and am havging trouble w/ insomnia, but will wait and see if it goes away.  this is life changing for me as for the first time i was actually fired from a job i had for 9 years right after finding out my work issues were largely do to add, even though i advised them of my condition and that i would be improving.  i am in a new job with an employer who is much more caring and i&#039;m doing better now that i have found a medication to help me.  by far positives of this medication outweight the negatives."
