Not only could you benefit from cleansing as Tracey outlined, but you need to learn about and utilize proper nutrition as wll as other sound health practices which harmonize mind, body and spirit.
I recommend The Body Ecology Diet by Donna Gates. It's basically a high alkaline diet, non mucous forming and very vital in nutrients. This would be a great start along with the cleanses.
Do you eat sugary items like pop, candies, cakes? How about chips, etc? Do you smoke or drink? Not for long if your serious about your health.
Every moment we either take one step closer to health or one step closer to ill health. You decide which direction you want to go.
Tune into your inner voice and see what it's telling you.
This may be the opportunity of your lifetime. I truely hope it is.
