I just have to say that is such an impressive display of true dedication and fierce discipline…you must have a great brain, hope at the end of your journey this go round you are happy with the body that goes with it 
I am brand new, did a bunch of research friday, began to fast that night after dinner. I was only going to do 48 hrs as my initial fast, but got to 50 and feel surprisingly good and at this stage of the game that HgH is large and in charge and doing its thing. So I popped for 72.
I am not hungry at all, havent been at all, not once. Unfortunately when people mention insomnia it really is a thing, I couldnt sit still hardly let alone be lying in bed flipping this way and that. I just hope it doesnt like continue for too long as it was a real stinker. I have no doubts that I can handle extended fasts, but I think 3 days is a solid start, they say you gotta crawl before you walk…best of luck in your endeavours
