15 weeks down and run out of oomph

I have been doing so well, 15 weeks on the mfp journey and now I feel like I have run out of steam.
I am not doing so well at logging everything past lunch time, I guess I am feeling 'bored of it'. I am not doing so well at completing my workout dvds. I am not doing so well at portion control.
At least I am not choosing junk food, so that is something. And I am still losing weight, just very very slowly.

15 weeks done and I can't hit the elusive 10 kg lost, I am sitting at 9.3 kg lost, which is great but I just want to be on the next part of the journey iykwim. I am not even at half way *sob* and yet I just want to be at the next leg now.

I guess a lot of the problem is that I still can't see myself getting to 20 kg lost.... I wonder if I can get there, and I get the feeling that the next part of the journey is going to be harder as I have been getting the weight loss and lowered calories through the obvious easy things, and now I need to dig it in for the lifestyle change.

Any words of wisdom for me? How can I switch it up?
