Hi , I am new to this web site and was hoping someone out there can give me some tips about my side effects. I take vyvanse for my adhd and I noticed that everytime I take it my eyes feel like there playing tug a wor and my mouth gets really dry only wanting to drink water or coke not being able to eat not only that I can go a whole 24 to 48 hrs without sleeping like now. Is there anyone with such a similar effect???
