I am in the almost exact same boat as you! I lost 30, got down to 128-started at 158 and am now at 149
I want to get back down to 135 atleast. More than anything I just want to be fit again and look better in clothes!! It is hard to get the motivation back the second time around because you know exactly what it takes, but it is hard to really put 100% in when you're so discouraged.
