"I am a 59 year old man. I have taken Adderall 30 mg. 3x daily for about 4 years. I am very happy with its performance; it has changed my life. It's hard for me to imagine all those years of struggling I went through before I was properly diagnosed. I tried Vyvanse 70 mg. for one week. Although it worked in a fashion similar to Adderall, I feel as if I have better control taking the medicine 3 x a day. The Vyvanse would wear off and then come back and start to work again and I found it disconcerting; it was like a roller coaster. With Adderall, I can expect it will begin to wear off after 4-5 hours and I simply take another one, usually before it has lost its effectiveness, and I feel the same all day."
