Hey Emma,
Try not to beat yourself up about it - it wont help!
You have some dates to aim for which is nice, how about instead of trying to lose x amount by that time to just try to make sure your 100% and comfortable that your fully in control by then?
You know the weekend is your problem so start looking for solutions... if its because you like to pick at food get some picky foods in (seafood sticks, fruit, mug shots) if it because you like to eat more things that 'seem naughty' then make some potatoe skins and scotch eggs. If its because you and OH are having me time then take some scotch eggs, salad, wholemeal sandwiches, chicken drumsticks, SW quiche and go and have a picnic. Or make some home made burgers.
I also think it might help to discuss this with your OH. Does he want to help you with the journey, does he support you, does he understand the plan? If you know where you stand with these things and explain that you need some extra help at the weekend and maybe an overview of the plan he would be able to help?? If he's a cooking man then you could maybe make some recipes together, decide which are your favourite, even have a curry night made the SW way or low syn chinese take away?
These are just some ideas hun, i really struggled at weekends too - i still do sometimes but having my OH there to give me a shove when i need it really helps
Hope everyones having a good weekend, im going for a meal with my dad at 12, going to either have fish or chicken breast - not sure which yet
i havnt had syns today yet but am goin to do my best to keep it to a minimum!! Then off to the pub to watch the Chelsea v Man U charity shield
OH is very VERY excited to watch some football haha
