Lisdexamfetamine
"I have huge attention issues and I've been taking Vyvanse since it first came out about 5 years ago and it's the only medication that works for my ADD. My dosage is the max at 70mg and it works great. The only side effects I've ever experienced is when I don't take it (usually on the weekend), you'll have an increase in appetite and you may become pretty lethargic. It's completely bearable though and it's nothing major at all. Other than that, I honestly believe it's the best one out there. With my insurance and the discount card from the website, I'm only paying $35 for my prescription. Everyone is different but it's definitely worth a try. I've recommended it several times. Ask your doctor about it and see."
