Valerian Root is a natural supplement that is an effective relaxant and sleep aid. It is similar to valium in effect, but non-addictive. It should be taken before going to bed. Valerian in combination with melatonin helps to counteract the wakefulness effect of galantamine. If later in the night you experience insomnia due to galantamine, a 2nd smaller dose may help you get back to sleep.
