I know a lot of people who lose down to about where you are and then just hang out for a while. Nothing wrong with that. I think it's amazing that you maintained!! for that. Now you are ready to tackle the rest of it!! Glad to have you back!
What Sandi said. I hope you are not beating yourself up over this. I have practiced "premature maintenance" several times and I have a feeling it will help me when I get to my goal and am on maintenance forever.
