Ah, if I had a pound for the number of times I've done that, well... I'd probably be able to afford a place in Cyprus too, LOL.
Never mind. It's just a couple of days and pretty much all you'll have gained--that's if you gained anything--will be a pound or two of water weight which will come straight off once you get back to it.
So, draw a line under it! And when you're ready, just climb back aboard!
