I should also have emphasised in my previous review, the importance of detoxifying and drinking lots of water! The toxins produced from die-off are what cause one to feel bad - headaches & other aches & pains, lowered mood etc., which is why I was recommending going slowly, to keeps those reactions at a bearable level. Really listen to your body, and go at the speed that your body is comfortable with.
Burbur and Parsley are recommended for helping detoxify & reducing die off reactions. I personally found Dandelion tea to be most effective, and was most amused when I realised that that is of course 'Wild Endive'!
