narcolepsy
"I was constantly struggling to stay awake (sometimes when driving too) and I'm pretty sure I almost lost my new job (started in 02/2009) before training ended. I'm also sure that they doubted I'd be very effective on the phones after training. Also, at the end of training, we had to make an 85% on the final exam to continue to be employed there and I'm sure they thought I would fail. Right before the exam, I quit taking Lyrica, which decreased the severity of the sleep narcolepsy, but didn't eliminate it. Vyvanse has greatly improved my effectiveness at work and I even got a promotion less than 3 weeks after I began taking it! I've had basically no side effects and now with not having to fight to stay awake, Vyvanse relieves a lot of stress and anxiety!"
