I know that before I TTC DD2 I did a 2 week detox starting the day AF arrived and stopped when I was due to O, DH tried it as well and we were fairly successful. We were trying naturally though. It did make me feel heaps better - after the first 4 days which I felt terrible. But if you can get through them you will feel fantastic.

There are some books and online info you can look at for a smaller 'cheaper' option for a detox, rather than shelling out all that $$ straight away
