The wait for the weight is over

I have finally reached my goal weight - 137 pounds (actually 136.6 to be exact). I have to admit it feels so good to be back into a size 12 pants and medium shirts. It took five months of slowly learning how to eat properly - and putting that into practice. I thought about it all this weekend. Will I go back to my old eating habits over time? Can I sustain this weight? Only time can tell.
