Have you ever tried detoxing?

Lately, I have been feeling sluggish and unhealthy. I have decided to take a week long break from drinking and smoking. I have been doing some research and have also decided to eat healthy (raw fruits and veggies, no coffee, limited sugar, etc…) during this time.

I was wondering if any of you have tried a detox diet like this before? Do you have any suggestions? Stories? Helpful hints? Recipes?

I am very excited to start this as I feel my body really needs some help and I would love your input :)
