master clenase day 5 vomiting, help!

I just joined because it's my first cleanse, and I'm hating every minute of it. It's the morning of day 5, and as soon as I had finished my morning lemonade (which, BTW, I think tastes gross!) I began to feel nauseous. Within 20 minutes I had to run to the bathroom to throw it up. I haven't felt good the entire time; headaches, fatigue, lightheaded and confused. I have been losing weight, which is nice, but this is the cost? I think I need to quit. What should I do? Can I eat food, or do I still need have a day of veggie broth, or juice? I need advice, cleansers. I really wanted to see this through to completion, but I feel so sick. Just some info about me and why I decided this... I am a healthy (pleasantly plup!) 30 y.o. woman, and my healthy habits have fallen by the wayside. I have been eating a lot of junk, plus drinking coffee all the time, and drinking a lot, and not exercising. I gained about 12 pounds this year. I thought I was the perfect candidate for this. Okay, thanks for your help.
