As temporary fixes for halitosis you could try liquid chlorophyll and/or more sparing use of activated charcoal (just make sure you do not breathe it in).
These should both absorb (or adsorb) toxins released from Liver Flushing so you won't feel so ill.
Eating cleanly and drinking lots of water (with lemon if possible) will help.
I would imagine as you cleanse your organs, your health will be reflected outwardly in many areas.
