narcolepsy
"I am diagnosed with Bipolar, ADHD Inattentive Type and Narcolepsy without Cataplexy. Modafinil generic or Brand name is very effective in uncontrolled daytime sleepiness without disturbing nightime sleep as long as it is not taken too late in the day. Helps with depression and focus and general energy. It literally saved my life by stopping me from falling asleep while driving and saved the lives of others. Generic is still pricey and the Insurance will not want to pay for it."
