That's good weight loss, especially for your starting weight! It doesn't get much better than that I'm afraid and Water Fasting is the quickest way to do it short of cutting off a limb. ;) (don't try that at home by the way kiddies)
When I first started my current fasts I didn't go near the scales for about 2 months after. I really needed to get down past my previous abortive attempts at weight loss before looking at them so as not to discourage myself. Maybe if the results aren't helping you could try checking the scales less often, or even wait until the end of the fast to find out? In the meantime just enjoy the changes you can see and feel which are much more important anyway. :)
