Energy level is low....

Now I am reading that a lot of people feel their energy soar on the SB diet, I am not one of those people. I am currently exhausted... Wow, I completed day three yesterday. Took a walk to pay my bills, that was around three miles. I have not felt like going to the gym all weekend. But I have worked out here at home. Stepped on the scale I have lost 7 pounds, but it seems too fast. I don't know if that is where my energy level is going? I need to get back to the gym today, I miss the gym. Perhaps my Sketchers are helping too? I'm not sure gonna tweek this plan and see if I can rearrange some high energy good before the next time I work out... Bluck.
