Hey Laura!
Welcome. I'm pretty new myself. I sure understand what you mean about getting some support - It's making a huge difference to me to hear other peoples successes and know there are others who are heavy like me, but who are taking on the challange.
It's awesome that you lost the weight once - you KNOW you CAN do it again! I wish I could tell you it'll be easier this time... but they might have to can me for fibbing

But it IS doable! and I hope the support of the group helps keep you on track and motivated the way it has for me.
I'm older - 45 - and don't have a baby to motivate me, but I'm about 308 and want to get down to a comfortable weight to ride my horses again, not to mention the health benefits.
Again, welcome! Hope to hear from you again soon.
