I've just started on my plan this weekend (yea, a holiday weekend - can you believe that??) so I can't speak from experience, but I certainly don't think switching plans could hurt you. Right now, I'm actually combining two plans - I'm counting calories with an emphasis on the Mediterranean style diet. So there are certain foods that I will stay away from, for the most part, while someone strictly counting calories has a bit more freedom than I do.
And totally off-topic, but I have to ask about your screen name, as I am a native of Biloxi. I don't currently live there, but I guess you could say I'm "Biloxibound" as well because we are hoping to retire there eventually. Most of my very large extended family is there.
As you can see, I added the Biloxi Lighthouse as my avatar.
