I hope you don't mind, but I thought a suggested menu, based on some of the things you are eating, might help to clarify what the others are saying ...
Breakfast: 2 Alpen Lights (HexB-1) and fruit salad
Lunch: Cold frittata and a big mixed salad (frittata is basically a hob cooked or oven baked omelette - made using eggs, 1 portion of cheese (HexA-1) and any combination of red/green peppers, onion, courgette, asparagus, tomato, mixed herbs. Make it when you have time, allow to go cold and slice into wedges). For a dressing you can use (measured) extra light Mayo (synned) or (as I do) seasoned fat free natural yoghurt (free).
Dinner: Leeks and mushrooms gently sauteed together using frylight then mixed with 1/2 tub Low-Low cheese spread (HexA-2) ... place in oven proof dish, sprinkle with breadcrumbs made from 2 small slices of wholemeal bread (HexB-2) and bake in oven for 15 minutes. Use to top a Jacket Potato and serve with grilled tomatoes and 2 Linda McCartney red onion and rosemary sausages.
If you need to snack between meals then snack on raw or cooked vegetables and raw fruit and don't forget that if you are using both HexAs in meals then you will either need to do without a milk allowance (ie black tea/coffee etc) or syn all milk that you use.
Being organised is the key - you can't just 'wing it' or you will be setting yourself up to fail, so I really would recommend doing a meal planner for 2 weeks at a time (making sure that you have included your Healthy Extras and snacks etc), then shopping to the meal planner and sticking to it
Also make sure that you
measure your Healthy Extras - if you try to do it 'by eye' or guesswork (ie when out and about) then it's inevitable that you will be going over your allowance.
Personally I choose to only use 5 syns and swap out a lot of starchy carbs for superfree veg as I don't lose well on starchy carbs (potato, pasta, rice, peas etc) ... so I would, for example, have half a baked butternut squash instead of jacket potato, or courgette and carrot ribbons instead of pasta, but that's my own choice based on trial and error to find what works best for me.
The thing about SW is that it isn't a diet - it does force us to make lifestyle changes and eating at coffee shops etc is something that just isn't compatible. Like a previous poster I'll happily meet with friends for lunch and thoroughly enjoy their company - but I won't eat there! I eat beforehand and just have a black coffee and great company
