Hazel, a holistic lifestyle that can be made to work for YOU is important in getting or retaining health.
There are many ways of doing so, and you need to find ways that are the best for your body. I've regained my liver health and I've never done an enema, and don't plan on it!
Cleansing is one of the MAJOR steps in a holistic lifestyle. I am single and work too. I had to find a colon cleanser that would not only clean me out, but rebuild my digestive track. Lower Bowel Balance allowed this while working 4-10 hour days tied a computer phone by my ears. I had days off when I could flush, of course. An alternative flush such as the plzchuckle hot lemonade flush might be perfect for you. It's a 2 week process with a one week wait afterwards then begin again ... and it's also working on other cleansing processes at the same time.
