- It produces sedation, an anxiolytic effect, and hypnotic properties, similar to barbiturates.
Peak character
- At its peak, effects include a heady dreaminess, mild sedation, lethargy, and a zoned-out, weary feeling.
- Pain is reduced, and relaxation is present, but without significant mood elevation or euphoria.
Negatives / side effects
- Serious warnings exist regarding interactions with alcohol and opioids.
- Addiction potential and other adverse effects are widely cited.
Aftereffects / comedown
- Effects fade after a few hours, leading to a readiness for sleep.
- Next-day effects include minor sedation or placebo; sleep may be disturbed on subsequent nights.
