I'm on my 8th day and to be honest i feel utterly horrible. I have no energy at all i can barely make it up half a flight of stairs without having to stop. This is the worst day so far and i Just dont understand why its happening now. All my collegues were really worried about me and they started saying this is really unhealthy etc I totally believe in this and really want to continue but i really need to know is this normal? Has anyone else ever experienced this?
