I'm almost through my last pack of cigarettes, and I haven't found my brand anywhere around here, so I may join you in giving up smoking, I'm already in the gym six times a week (Moevenpick gym, they have a promotion now to take on new members...) but a detox diet sounds horrible!
Let me give you some of my favorite diet suggestions instead:
1. The vodka diet (works wonders)
2. The icecream diet (especially in summer here it seems a good choice)
3. The tuna diet (works really well, but is pretty hard to stick to)

Goodluck!
