Thanks for the invite Sally, @Sallyo. I had written a long acceptance post a few days ago, but it got lost when the wifi signal was not strong enough to load the message and it has taken until now for me to write another post...
I will join the challenge once I am back from my travels in early July. I am in Sorrento, Italy at the moment, moving on to Orvieto tomorrow. So far we have visited Rome, Sorrento, Capri, Positano and Amalfi. It's been fabulous - so much of interest to see and lovely warm weather too, though stormy in the late afternoon. I can't find words to properly describe how wonderful it is to see the history in evidence in Rome. And the Mediterranean coastal towns are so spectacular!
I will certainly need the challenge when I get back. I can almost see myself expanding with every bit of food I eat!!!

All my clothes are tighter, and we have only been away 9 days!!! It is impossible to eat the mainly vegetable diet I am used to (which normally helps me keep my weight in check because I can satisfy my hunger by eating lots of veggies) as there is just no access to these foods. And I find I feel the need to eat more when travelling than normal - and it is not because I am more active. I have been able to buy some carrots and tomatoes, and some apples, which is something, but when I have ordered a salad as a meal, it is about one-fifth (maybe even one-tenth) the quantity I would usually eat. So I am eating more bread, more cereal, more cakes (...!!!) and less protein than I usually would.
So my challenge will be to get back into healthy eating regularly on my return, and to fast when I feel that I want to, with the aim of feeling comfortable with my body/weight again (and not have the horrid bloating that I am living with each day, probably due to the higher sugar levels than usual in my diet).
Best wishes and good luck to those of you who are already active with the challenge.
