I started on a Colon Cleanse before reading your article.
Yes! I too have been experiencing old emotions and thoughts. Spent the first day being "Weapy" and "Teary Eyed" without knowing why. Now it makes sense.
Sure will feel good to get rid of the emotional garbage that I know still affects my moods, descission making and energy levels.
Also too... experienced erratic intermitent headaches which I'm sure are from the release of stored chemicals.
