There is a great video on how to do an enema at
http://www.youtube.com/watch?v=SD1QzlKkz_s in case you are interested. I like to use my bibkit that I got at
www.bibkit.com. I know, before I did them I hated the idea and avoided doing them for the longest time. I feel so great afterwards and even during - because I can feel I am dumping so much that was weighing me down. Also, check out this webpage
http://www.30daysraw.com/ and look at Episode 9 - there is a great video there that explains what a colonic is.
If you want to detox without doing colonics then I would suggest a high raw diet. Angela Stokes ate high raw for 3 years before switching to 100% raw and gained health & lost weight during those 3 years. See
http://www.rawreform.com/content/view/17/41/. Eating high raw slows down the detox so you may be able to avoid colonics. But I agree with Matt as he says in "Raw Success" that to be successful on a 100% raw diet you have to drink green juices and do colonics.
Many people do fine on a high raw diet for life also. Just avoid the 2 worst foods completely - refined sugar and starches.
I'm glad you are feeling better!
