What kind of a doctor prescribes provigil/similar meds? What are the indications? I have sleep apnea, persistent fatigue. Use cpap nightly.

Provigil use. A sleep medicine specialist can prescribe Provigil or similar stimulants. They are indicated for narcolepsy or other disorders associated with excessive sleepiness, such as sleep apnea. Fatigue can also be helped with Provigil or a similar drug nuvigil.
Hypersomnia. Physicians trained in neurology, psychiatry, and sleep medicine frequently prescribe wake promoting medicines. Some primary care physicians are comfortable using these medicines. If you are not seeing a specialist i would discuss this with your primary care first.
