Hey there, and
Have you ever considered that the reason you're on a yo yo rollercoaster is that you choose plans that are ultimately not sustainable, like Master Cleanse? You might have better luck and more success at maintenance if you picked a healthy eating plan, incorporated exercise, and committed to keeping those healthy habits for life, into maintenance. If you pick something not sustainable, as soon as you go "off" the diet, the weight comes back. With sustainable lifestyle changes, you never go "off", and so maintaining is much easier.
In any case, jump on in. Can't wait to get to know you better!
