"I have severe insomnia. I've tried dozens of benzos, z-drugs, and natural supplements, and this is the only medication I've taken that allows me to fall asleep before midnight. I got a solid 5 hours of sleep on Phenobarbital. I didn't like though how I woke up so early in the morning... I feel my best when I get 8 hours of sleep. I probably need a higher dose next time"

"Phenobarbital (five 32.4mg tabs = 162mg) is an excellent sedative. It lasts the entire night although it does cause next-day sedation because of its very long half life. I wake up periodically but always fall back asleep and get 7-8 hours in total. I have found the OTC supplement 5HTP to be helpful in conjunction with the Phenobarbital. Please beware of tolerance, dependence, and rebound effects. I would not use the drug for more than 7-10 nights at a time (with 2 week breaks). During breaks, I use other medications to help me sleep that do not have cross-tolerance with Phenobarbital so that tolerance to the Phenobarbital is reversed periodically."

"Took 50 mg at bedtime, it actually acts as a stimulant and keeps me awake. Fast heart rate, body aches & a slight headache. I will never be taking this for sleep again."
