Regarding cleanses, which one are you doing...
I can recommend Arise and Shine by Richard Anderson. I had done The Master Cleanse for 14 days with not much leaving my body but I felt good, then I did raw foods for about 5 days, then I started Arise and Shine and felt unbelievable...BUT...
no matter how good you feel while cleansing, whatever cleanse you do, it is SO VERY IMPORTANT to deal with underlying emotional issues, I cannot stress this enough.
Emotional issues need to be the addressed. And cleansing is the best time to do it because you are more open. So I say this again no matter how well you feel on your cleanse and you will feel emotionally and physically quite good, please investigate those issues you sense lie beneath the surface ...
