Dear SIir, I have suffered from fibromyalgia syndrome for several years and have many symptoms. These include chronic pain and sleep deprivation and in recent times, heard a radio discussion on the benefits of Withania(herb) in relation to chronic sleep issues. I have been taking Amiltryptiline(endep) (20 mg) per night for more than two years with ever decreasing benefits. I would like to know, can i take withania ,and the current drug(ENDEP) and remain safe!! I look forward to your assistance with the above, Kind regards, R.Byrne
