Running on empty can become an addiction

So before I divulge further into what I really want to talk about I just wanted to say soy milk or at least chocolate soy milk taste pretty good ( I always thought it would be gross tasting). Anyways I wanted to share something: once you start a fast it feels like it gets easier and I've noticed that sometime after awhile you get this weak haze feeling, like you are not all there and it kinda feels like a high :/ so ya it kinda feels weird/good LOL probably not something I should like .... It's weird but what can I say? Also protein shakes are AMAZING, they fill you up so quick and a 450 ml bottle lasted me 2 days :D and it contains nutrients and whatnot so it's almost like a meal replacement ... perhaps ? So I would so drink one a day as a sort of liquid fast for a week or so but they only sell them individually for like $3.96 per bottle .... so just a bit pricey :S
