"i am a 22 yr old female. hated the significant side effects of vyvase60mg. hated invuniv. love the patch. allows me to control the medication. i usually take it off about 7 hours after putting it on. this allows me to sleep at night. i can focus at work very well and no significant drop. i realized i cannot blow dry my hair, or go tanning with it on or i would get a big burst of medication! sometimes have a hard time sleeping if i don&#039;t take it off early!"
