I love juicing! Some of the combinations that you think won't work do surprisingly well and it's a wonderful way of getting lots of nutrients.
Honestly, I think you should be proud and you seem to know what to expect in terms of realistic long term weight loss.
I've just trudged on with my 1-2lbs a week for a year and have somehow lost 2 stones. It's very pleasing.
Anyway, off for a run!
