As long as you enjoyed it!!
I know how you feel, I go away in a fortnight and know I will put at least 4 pound on. I kind of try for a day or so but always falter. I can't resist croissants, puddings and afternoon tea and cake!!
I'm not going all inclusive again after this holiday!!
The best bit is that you are back on the wagon, in days gone by I bet it would have stayed on, I know it did with me!!
Ps what was the weather like in Lanzarote? I'm going to Tenerife.
