So glad you're ready to plunge into your journey!
Like you, I'm a divorced mom of two sons. Mine are now in their 30's with their own families, so I cook just for myself. Whatever stage of family-sizing we're in, we can find a way to make this journey work for US. (Yup, when my boys were young, they were athletes and needed tons of carbs and proteins for their ever-skinny frames so I must say my life is easier to manager these days. lol)
Are you going to restart the SP Diet Stages? I do recommend them, especially because Stage 3 helps us really explore our ingrained habits to make changes in areas we don't even realize exist.
ENJOY the journey to YOU!
