I saw in addition to Emergen-zzzz Pm another natural sleep aide that can be bought at wallgreens now I can't find the name. I am Diabetic an in the last week I don't sleep and ending up sleeping til 12 and 1pm this after no sleep til 4 and 5 am. Prior to that I had very low energy during the day and napped in the afternoon, now my days and nights are very off tract. is the Emergen-zzzz a safe natural help for me?
