Wow, that's great! Must be nice to see such changes occuring in your life!
Your weight loss will probably slow down, but I can tell you from experience that the later kgs are much more visible than the first ones (it's also logical, think about peeling an onion. Every peel you remove is smaller.
I lost a bit slower than you (1 kg/week), and have lost 8 kg in the last 8 weeks, and it makes such a big difference. Can't imagine what the final 10-14 kg will do. But I expect my weight loss rate to drop to 0.5 kg per week eventually.
