Onward ho (or whatever they say.) Sounds like you had a great time and that 7 lbs will probably be gone after a week of good eating. Why not just start back where you were and see how it goes. It's still just Stage 1 (I think) so I don't think it really matters.
Glad you are back and ready to get going.
BTW, we are all at different places. Some people have been sick, others started a couple weeks early
, and it really doesn't matter.
