Hiya,
I felt exactly the same this last week... I joined up 3 weeks ago and lost 4.5lbs in my first week. I was so happy and motivated I REALLY stuck to the diet the next week and even tried having no syns whatsoever!
At my 2nd weigh in I "only" lost a pound and I was devastated, I didn't even stay for the meeting as I knew I'd burst into tears when our consultant spoke to me.
I was ready to pack it in but I said to myself I'd give it a go for another couple of weeks to see what happens and then I found this forum and people have been so lovely and supportive...
This week I've lost 1.5lbs, again not a massive amount but it means I've lost half a stone over all!!
It might only be a pound or half a pound but all those little bits add up to something bigger... Whilst I'd wished I'd lost more this week I was so happy I'd lost half a stone that it didn't matter.
Just focus on each day and week at a time.
Personally I find planning breakfasts and lunches the most important thing as otherwise I'll skip breakfast and just grab a sandwich... but now I make sure I have a banana and other fruit for brekkie and babybels for mid AM snack (HEx) then chicken and salad (toms, cucumber, beetroot) for lunch and a cereal bar for mid PM snack (HEx). Then for dinners I either just have something very simple like grilled meat and veggies or I grab a recipe out of my syn free original recipe book... the moussaka was amazing!!
On Friday I had my first green day (I'd been EE before then) and I made an absolute mountain of syn free SW chips... I still can't get over I can eat all this food AND lose weight (even if it is "only" a pound!)
