insomnia
"I was dealing with severe insomnia for a few months. Dr prescribed 10mg. It helped me fall asleep noticably quicker. No sleepwalking or anything, but then one night my work woke me after an hour or so and I was slightly impaired; stumbling through bedroom and slurring words. Felt like being drunk except that my mind was still fine, just body delayed. Otherwise,  it has been free of side effects and gets job done - except for heartburn. Experience it nightly after taking ambien and take an antacids"
