I am a very big fan of following structured training plans that are fitted to your current fitness levels. Each workout is effort, and I always go into a workout with a goal, and knowing what I want to achieve. Results are seen through consistency, and if you are following different plans, you are not going to get consistency. Early on, you will see a lot of results, but they will slow down quickly. As for the fatigue, I still battle with it every now and then. In the beginning of my training plan, and now recently at the start of a new training block (intensity has ramped up). It takes a week or so for me to adjust, and then I feel great. I do eat really well and clean however. I drink very sparingly and avoid processed foods/refined carbs (I still fail sometimes though - those long swim sessions are killer).
