It's more than just being tired.

Chronic sleep inertia syndrome (CSIS) is a real medical condition affecting an estimated 47 million Americans. If you experience prolonged grogginess, impaired alertness upon waking, or reduced morning cognitive function lasting 30 minutes or more after your alarm goes off, you may be living with CSIS.

You deserve mornings that feel like mornings.

A targeted approach to waking up.

VIVAYZIO® (somniclarin sodium) works by selectively modulating cortical arousal pathways during the sleep-wake transition. Unlike traditional stimulants, Vivayzio does not increase baseline cortisol levels or interfere with natural sleep architecture.
