"i started using this medication about 4 months ago. i was diagnosed with adhd when i was 5 years old. the only annoying thing about this medication is that it keeps my mouth extremely dry. i found that using hard candies (regular or sugar free) helps a lot. vyvanse has helped me a lot, especially with my concentration. i can actually read a book without having to read the same page 3 times, but the only thing is that it feels like my blood pressure goes up, i also have tachycardia.
