I consider myself a relatively healthy person. I get 7 or 8 hours of good sleep a night. I eat consciously—by that I mean I’m not a strict dieter, but I generally make good choices. No doubt, I enjoy a good night out and a nice meal, but everything in moderation. Most weeks, I’m a 3-times a week exerciser and I walk the lengths of Manhattan every day. Simply put, I’m not extreme in either direction.

But lately I’ve been feeling sluggish. I haven’t been sleeping well and consequently have trouble getting up in the morning. Things haven’t been…regular (TMI?), and my appetite is all over the place—sometimes ravenous, sometimes totally disinterested in food. Just to quell the rumor mill: No, I’m not pregnant. (I’ve had a few people ask me.) So, why do I feel sapped of all my energy?

Recently, I had some of my dearest girlfriends visiting for a week. And of course, we ate, drank and were merry all seven days. My normal bedtime went straight out the window as we talked and laughed until the wee hours.

While my girls were here, my husband hasn’t. His well-deserved vacation couldn’t have come at a worse time—we’re moving! With Andy away, the task of apartment hunting, decision making, and lease signing was left to me.

As soon as my friends boarded their flight back to Europe, I boarded one to Haiti for a work trip. In Haiti, we have early mornings, late nights, and grueling car rides through the countryside. When I got home after that I all but collapsed. The weight of the previous weeks was finally taking its toll.

What I’ve learned is that these disruptions to my schedule and lifestyle have a significant impact on the way I think and feel. And if my life is making me feel like crap, clearly I need to make a change. So, I’ve decided to start a cleansing program. For the next few weeks, I’m cutting out caffeine, sugar, and alcohol (at least on the weeknights!). I’m getting rid of all those things that falsely keep me going when my body is too tired or too stressed to function. I’ll trying to eat only unprocessed whole foods, getting to bed early, and not allowing my work to drag into the evening.

I hope that in a few weeks I’ll be back to equilibrium. Because when I’m not feeling good, life is not as good. And I want life to be good!
