Welcome to the forum and welcome to the plan !!
I do know that seeing the scale read : "weight-loss" is very encouraging, and weight-loss seems to happen quite immediately for people. Hope all goes well !!
Also, have you purchased the book "Success in a Shaker jar" ? It has tips on how to go about the program, especially if you are not sure you can stick to it for the full length of time. They even suggest breaking up your weight loss goals into mentally-manageable chunks, and then reassessing your program after your first goal is reached, if that would be helpful to your overall mentality. You may find it helpful to read.
Plus, this forum is an absolutely wonderful support-opportunity for you on your entire journey.
Best wishes on your new and DESERVED adventure,
Karli
