I'm also not sure how long my Master-Cleanse will be, but I have promised myself and committed to not eating again until at least June 1st. I need to be back on solid food (raw) by June 10th, so I'll break this some time in the first week of June. However, I may switch to a juice fast at some point. Just going to go with the flow for now. As long as my body doesn't demand any food, I'll listen to it.
