I would not recommend trying anything drastic. The only people from whom the weight "just melts off" is people who have a lot of weight to lose, and don't have any medications, ailments, etc slowing their metabolism. It's rare. Once you're within 20 lbs of your goal weight, it is a battle. Why? Because technically, you're already at a healthy weight. Your body does not give up it's last fat stores easily at all.

Congrats on your success so far.

...but it's slow-going here on in. Be patient; the faster the weight comes off, the more likely you are to regain it!

Hang in there!
