I have been taking this product along with Venom Hyperdrive 3.0 for about A month now and I have to tell you this stuff really puts you to sleep.  
   
 I try to take it about 30 minutes to an hour before I am ready for bed. Thats about all the time it takes to put me out. The first week or two my hands and feet would feel A little tingly right before I fell asleep. I have not felt that sensation since, and when I wake in the morning I feel refreshed and well rested.
