Lots of good advice above, in this thread.
For an exercise regime, I'd say mix different exercises to prevent the body developing a resistance to one type of exercise. If you're really 'set' in your jogging regime, then keep with that. I'd say that losing 8 kilos is a considerable success - keep it up, you're doing great!
If you just keep to jogging, your weight should continue to drop, but this process will slow a bit with time - why not alternate it with aerobics or some strenuous martial arts class, say twice a week. I recommend joining a cheap class if there's any nearby, especially if you think their routines are strenuous (ask to observe a lesson) - this way, even if the aerobics/martial arts class is only twice a week, you'll still be varying the training your body's getting, and it won't be used to any one regime. It should help your weight-loss.
Another nice thing about a class is that with a lot of people working together, it's easier to 'go along' with them, and so you can push yourself harder.
A training partner is another cool idea, but he/she's got to be as dedicated as you, or it will ruin your own exercise program (nothing like an irregular partner to do that).
Later on, when your weight has dropped to a level you're happy with, you could consider adding weights to your exercise program for strength training as well. For example, do your jogging/cardio on one day, and medium to heavy weights (whatever you can manage) on another. This will build strength as well as endurance - I really believe in all-round training for perfect physical fitness.
Hope this was of some help. Take care.
