Narcolepsy
"I found myself sleeping all day against my will and it was depressing to be so unproductive. After I was accepted to vet school, I knew I needed to figure out why I was so tired all the time. I was diagnosed with narcolepsy without cataplexy. I immediately started Nuvigil in an attempt to get regulated before I started school. About a week in, I experienced  anxiety, and a racing heart on a few different days. My symptoms soon subsided, and I found my quality of life drastically improved. I take it in the morning before class, and I was able to stay awake all day with very little problem. I still have good days and bad, but my worst day is still better than my life before it. I am so thankful for my doctor and Nuvigil."
