Bacopa-Ginkgo Brain Strength, 60 tabsstar rating 5NadiraApril 29, 2009Due to Fibromyalgia and CFS, II have been unable to sleep for over 20 years. My concentration was greatly affected and it was very difficult for me to come out of my brain fog. Within a week of taking Bacopa-Ginkgo, my sleep pattern started to change. I was sleeping longer and my concentration greatly improved. My experience is that taking 1-2 tablets an hour before sleep has changed my life.
