Have you ever considered simply going on a fast for a couple days? I've done it before and came out of it feeling great. Its interesting to note that virtually every culture on the planet incorporates a regular ritual fast... except for the modern West. So it certainly has the weight of tradition behind it.
There are a couple different ways to do one:
1) A 48 hour strict fast of nothing but water.
2) A 3-4 day fast of nothing but whole grain bread and water.
3) A 1-2 week fast of nothing but fresh fruits/vegetables, whole grain bread, and water.
I've only ever done the first one, but I've known people who have done the other two. They all say that the key is to eat truly whole grain bread and the freshest organic vegetables, as opposed to commercial breads (that are pumped full of preservatives) and commercial fruits/vegetables (that are covered in pesticides). Might be something to consider.
