Don't be so hard on yourself. It's like you're punishing yourself. This is not an easy thing to do so don't feel like a failure. Food is a very comforting thing and when you have so much on your mind I am sure the last thing you need is to feel sick too! But it's not the end and tomorrow is a new day. Whatever you do don't put such a hard strain on your body by going on off on off. Take your time. Think of the Master-Cleanse as a good thing. Not a denial of food or of comfort but a way to give yourself time to relax. I don't need a degree to know that your body must produce nasty substances when you stress and worry and mostly when feeling alone. I am sure you have felt your heart literally ache at times. But this is you and today is a beautiful day out and you are fortunate enough to have a tomorrow to look forward to sssooooo stop beating yourself up. I am sure if you have been through ups and downs in life and are still here it is because you are strong not weak. I am sure that if you are so determined to do the Master-Cleanse is because you love yourself and want better and that's all you can ask right now. Alot of the Master-Cleanse is mental ( I LLLUUUVVVVV FOOD FOOD FOOD). The cravings and such, ofcourse there can be physical hunger but you take a swish of lemonade and you slurp down some water and that passes. I myself got a good book and I've been to the park the last two days and I'm off again today ALONE. Just a sheet and me amd my MC with a good book under a tree. Cheer up!
