insomnia
"I take this to help me sleep.  I was started at 50mg 1x day at bedtime with no effect. The dose was increased to 100mg 1x day at bedtime with some effect.  The dose was again to my current dose of 150mg 1x day at bedtime and now it works great!  I wake up ready to go after 7ish hours of sleep.  Works better if taken with a light snack."
