I also have periods where my energy goes way, way down. You might want to explore various programs, and post a few typipcal menus so that others can see if you need to tweak your intake a bit.

BTW, are you getting plenty of rest too?

I've been losing inches rapidly by doing my cardio (walking 3 miles) first thing in the morning and on an empty stomach. I can't believe how fast I'm seeing results...
