"been taking it for years. not as effective as at first. i sleep maybe 4 hours, then wake. take a 350 mg soma about 3am watch 30 min tv, awake at 6am like clock work. no groggy or med hangover though. better than ambian or lunista. i can take a fist full of those and watch the middle of the night programming. like others, never had a problem sleeping. i think interferon destroyed that ability, but i&#039;m alive and cured, so i&#039;ll take a little insomnia. hope this helps you!"
