Alright, on to the gory details that are part of every detox (feel free to skip to the next slide if you're not into bathroom discussions). From the start of this little experiment, I've had the runs. While I do get them every once in awhile, they stayed with me throughout the week. Sure the extra fiber that I'm getting from all the veggies could account for my frequent jaunts to the ladies' room -- but why was it not, you know, solid? I talk to Gittleman about my case.

"It seems like your body needs a major cleansing of some sort of pathogenic bacteria that's possibly yeast-based," says Gittleman. "This diet illuminates an imbalance in your system." While my body's reaction is not common, Gittleman says it's not necessarily a bad thing, and suggests I consider my bathroom unpleasantries as a "parasitic dumping."

To help stabilize the bacterial balance in my intestines (and as a result, get me back on a more, shall I say, normal pooping schedule), Gittleman suggests I add a probiotic to my diet.

The day I've been dreading has finally arrived: The juice fast. The plan is to drink a cup of "Miracle Juice" every other hour starting the moment I wake up until I go to sleep. I also have to drink a cup of water on the hours that I don't drink the cranberry concoction. Gittleman says this Miracle Juice "helps flush away toxic fluids, which can account for as much as 10 to 15 pounds of water weight trapped in our tissues," which is why people have claimed to lose up to eight pounds overnight on this cleanse.

Wondering what the heck is in this so-called Miracle Juice? Put this in your pitcher: 8 ounces of cranberry juice, 56 ounces of water, a bit of freshly squeezed orange and lemon juice, and warming spices like cinnamon (the cinnamon helps stave off hunger). And so it begins:

9 a.m. I start drinking a cup of Miracle Juice every other hour, pounding water on my "other" hours.

1 p.m. I'm surprised I don't actually feel hungry, even though the scent of my co-workers' lunches are wafting through the office. Note to self: Sprinkle cinnamon on my lunch to see if it helps me avoid a mid-afternoon snack craving, post-detox, of course.

2 p.m. I start getting a headache and ask my co-worker, Anna, if I can borrow her Snuggie because I am freezing -- they must be blasting the air conditioner.

3 p.m. The coldness isn't going away. I'm starting to realize that it's just me. Anna feels my forehead and says I'm burning up. I think I have a fever.

4:45 p.m. The fever persists, I'm peeing every hour, and I'm still not hungry.

9:00 p.m. I get up from the couch for my scheduled cup of water and feel dizzy after standing.

10:00 p.m. I still have two more cups of Miracle Juice to go through, but I can't do it. I'm used to feeling mentally drained at the end of the day, but today my body is just shutting down. I'm going to sleep.

Deadweight. That's the first thing I think when I try to get out of my bed the morning after my Miracle Juice fast day. Each step I take is a conscious decision to expend energy. I take a shower but trying to wash my hair leaves me breathless; bending over to wash my legs is exhausting. By the time I get out of the shower, I feel nauseated and queasy, so I decide I have to eat something. I'm shaking as I walk down the stairs, holding on to the wall and railing. I have scrambled eggs and water for breakfast and feel better, but the thought of walking back up the stairs drains me so much that I sit on the couch for 10 minutes. Once I make it up the stairs, my body chills come back.

While Gittleman says the initial experience of the one-day fast can be "somewhat uncomfortable," my experience is a lot more extreme. She offers an explanation: "You were drained of electrolytes because of the consistent diarrhea, so you were just depleted by that point," she tells me. "Quite honestly, not everybody should be doing the one-day fast." If you're on medication that requires food as a buffer, have problems with your kidney or liver, have blood sugar difficulties, or have mental health issues, Gittleman recommends skipping the fast day, which can clearly be traumatic for some people (myself included).

I'm officially finished with my detox diet and head back to Dr. Murad's office for a follow-up appointment. I'm anxious to see if this (somewhat torturous experiment -- especially toward the end) would pay off in some way.

Weight: 103 pounds (I'm 5 pounds down and my friends say my face looks thinner.)


Wrinkles: 26th percentile (Up from the 17th percentile -- not bad!)

UV Spots: 52nd percentile (Hurrah! Cahitas says this 9 percent jump is a significant increase.)

I'm honestly amazed to see such tangible results in my wrinkles and UV spots after just 11 days -- especially considering I had such a bad reaction to the juice fast day. But as I start to incorporate healthier, solid foods back into my diet, I start to feel really good. My caffeine cravings have passed (a true miracle), and I'm feeling more energized and upbeat. I'm not even thinking about my beloved Micky D's. That feels as impressive as the improvements in my skin.

Before I started this detox, I thought I would go on a fast-food, carb-heavy, donut-eating rampage when it was over. But now, after forgoing those foods for nearly two weeks, I'm surprisingly not craving them at all. I do, however, head straight to Starbucks for a venti iced coffee and savor each deeply-missed sip on my drive to the office. Progress, not perfection, right?

My best advice to you if you're planning on following this detox diet or another one:

Do it in the summer. Is it hard to miss out on vodka-spiked watermelon at friends' BBQs? Sure. But Gittleman says your body is more relaxed from the heat during the summer months, and therefore better able to release toxins.

Listen to your body. In hindsight, I probably shouldn't have done the juice fast. It was just too much on my body, and I suffered as a result. Gittleman agrees with this point, stressing that it's incredibly important to heed your body's signals before plowing through a set plan, which isn't what I did this time around.

Talk a friend into joining you. Luckily, my editor, Meghan, was on a detox diet around the same time I was, so we were able to commiserate. Check out her detox diary here.

As for me, I'm happy I got roped into this assignment after all. While it wasn't all fun, it certainly was enlightening -- and who knows, I may not even need someone to talk me into doing it again. If my coffee habit gets out of control and I find my car swinging through the drive-through too frequently, I may just dust off this book and have at it again.
