Vyvanse was fine for awhile me. Know I can secretly finish a 70mg 30 day bottle in 7 days!! I'm not a speed freak, but I have Ulcertive Colitis and the Humira knocks me out at work as my job as an editor I'm sober from booze since 2008, but fear I am the cliched pill popper with an excuse. The guilt is eating me alive. That's my experience. I just turned 50
