Lisdexamfetamine
"I've been taking Vyvanse for about a year now and it has been an interesting trip. At first I couldn't sleep for the life of me and would go days on only a couple hours of sleep that I could get. Then after a couple months I was able to sleep almost like I used to and I noticed that I was more mentally alert and energetic but, my appetite dramatically diminished to almost nothing and still felt like my body wasn't getting enough rest. On top of that, when I would skip a dose I would have EXTREME hunger where I couldn't eat enough and I would have terrible fatigue! After a year everything evened out and began to feel normal other than having no appetite, but I have a healthy food schedule so I don't forget to eat. I would also like to say that I think it should NOT be recommended for children!"
