I was so sad when this was out of stock for so long. I tried another supplement with similar ingredients but after switching back to taking Seriphos again was like night and day. This stuff really works. I wake up less and fall asleep easier when I take this with dinner. Don't hesitate if you have cortisol spikes at night, buy this now!
