insomnia
"The only thing that truly works for idiopathic insomnia and chronic/childhood-onset insomnia. Take it 1 hour b4 bed. The most optimal dosage for chronic insomnia is 15mg, the effects halves by doubling it to 30mg and also halves by reducing it to 7.5mg, although some people may find 7.5mg optimal for long-term tapering."
