I’m not going to lie: Day one of my three-day cleanse was pretty rough. The cleanse guidelines said it was OK to exercise (“Absolutely!! Can we please finally put to rest the myth that if you don’t eat a lot, you’ll lack energy?”), but I’m not sold. I’m one of those crazy people who wakes up at 5:30 a.m., runs five miles at a pretty decent pace, lifts weights and does some yoga before walking 30-odd blocks to work. I toned it down the day I started my cleanse, but those 1,100 calories weren't powering me through the day. By the time I walked home from work I was exhausted and a bit dizzy; I fell asleep at 9 p.m. and slept nearly 10 hours.

So, lesson one: workouts + juice cleanse = bad idea. That said, I was surprised that I wasn’t really hungry throughout the day. I actually could barely finish all six of my juices. Three of the six juices are a mix of greens (romaine, celery, cucumber, kale, parsley, green apple, spinach and lemon). Not being able to start my day with coffee (and now exercise) was hard enough, but starting it with a liquid salad was a lot to handle. Some hot water with lemon helped me get those three green juices down. On the positive side, the juices I got to drink in between the greens were really tasty. It was like I had something to look forward to after drinking my green stuff.

Juice number two, a pineapple-apple-mint, was sweet and refreshing, and the midday lemon-cayenne-agave tasted like a spicy lemonade. But the highlight was my last juice of the day, a blend of raw cashews, agave nectar, vanilla bean and cinnamon (which, unfortunately, had to be finished before 8 p.m., which is usually when I’m sitting down to dinner). It was like dessert and actually had some texture to it. It also had seven grams of protein that I think my body was craving (the others had at most, two grams).

I survived day one and day two (thank goodness for that cashew-nut juice), despite feeling a bit lethargic and cranky. One more day to go. My biggest problem so far is that I miss texture. I'm thinking of freezing my spicy lemonade and turning it into a slushy, just to mix things up.
