I once spent 6 weeks eating nothing but grapes. It sure cleaned me out, and I felt and looked much better for years afterward.
It is not possible to cleanse at a deep level unless you do a sustained regimen. Your body will cleanse itself, but only if it's given the right conditions for the right amount of time, just like you can run but can't reach the full speed you're capable of without the right amount of open space. You won't get anywhere near your potential speed trying to run the length of your living room. Likewise, a day or two will help, but won't get the deep crap out of your system.
Of course, it's a no-pain-no-gain proposition. It's monotonous, you spend a lot of time feeling uncomfortable, irritable, and even ill. It's not very rewarding in the beginning, but you get over manageable humps and spend a while feeling much better, with sharpened senses and a fresh appreciation of life. It's not an exaggeration.
Ultimately, you should eat the things you like. Having done an extended stint as a raw food vegan and a just-plain vegan, I believe that such diets should be temporary and part of a strategic cleansing regimen rather than a lifestyle. It's a bit like celibacy. You might be naturally inclined to shun intimate relations for a while after a painful breakup, but sooner or later you begin suffering from lack-o'-nookie and need to get a little. I think veganism is a bit extreme a dietary lifestyle to suit all but a few people. Still, most people could benefit a great deal from going vegan for a while.
M@T, if you'd done that to me, I could have forgiven you for everything except the curry. That was uncalled for!
Hang in there FB!
