Reading the earlier reviews I was a bit chary of this. Then I realised that people are expecting a quick fix for what ails them. This isn't one of those type of 'magic pill' ~ it takes time and after a few weeks I can honestly say that I am sleeping well and have more energy. So I would recommend it and buy again. There are almost three months supply and as I leave a month gap between taking any course of supplement that means I won't have to re-order until end September - very economical.
