I find saturdays hard, it's the only whole day the OH and I get to spend together, so we're usually out and about.. and he doesn't have to watch what he eats so we often end up eating at a pub, café or restaurant! Or nibbling on convenient food (If I don't have the foresight to take fruit!)
As I'm off sick, the days are long and boring so have to resist then, but it's counting time down until I see the BF as he finishes work at 2! So I'm pretty good with self control IF I can keep busy...
