I am usually away at Xmas with family so I stop weighing a few days prior and don't start again until I get back. It therefore shows up as a period of slope rather than step, but with no readings between the start and end of the period.
Xmas 14/New Year 15 is a very noticeable step that never really was lost. I went up around 6 or 7 lbs, or thereabouts. Xmas 15/New Year 16 is less noticeable and arguably near to recovered. There is a lot of "noise" as the readings jump up and down but I seem to still be around 2 to 3 lbs heavier, more or less, than I was.
Trouble is that although the general trend seems fairly level, over the longer term it is gently upwards. Annoyingly in April 2014 I was a mere 3.5 lbs away from my goal, but I never reached it. I'm now 29.5 lbs away.
Making a special effort (not 100% successfully) not to eat between meals now. Distracting though that is. At least I have some fruit in now for when it becomes too much, and hopefully that'll be less fattening: if less satisfying too.
