I wouldn't worry about how quickly you are losing the weight.
My husband lost 20 pounds after only 2 weeks and continued 1 pound a day until I beat him for loosing weight faster than I did. Men always loose weight faster. Especially if you've got more than avg. muscle under the extra pounds. Maybe you could think of adding a few more carbs to your diet so you have a little more time taking off those last few pounds. It'll help with maintenance.
