Blueprint Three-Day Foundation Cleanse
212-414-5741; blueprintcleanse.com
The 72-hour version of Blueprint’s Foundation cleanse is its most popular; it’s just enough to give you some time to reconnect, reflect, and apologize to your liver, but not so much that you feel like you’re a food weirdo who can’t socialize, or become annoyed that you’re picking up juices every day (which are freshly made and include spinach, cashew milk, and apple juice). For maximum effect, you should give up coffee and black tea, but at least the resulting headache is virtuous; $65 per day for three days.
