Drink a pint of water before bed, leave another pint next to the bed when you wake up with a drouth, when you get up in the morning, gargle with salt water first to cleanse your tonsils, lots of germs on them,when you brush your teeth in the morning, brush your tongue with a mouthwash containing chlorhexidine (mouthwashes contain this) and use a tongue scraper (It really works) because this is where all the bacteria that causes the halitosis lies, on your tongue, finish with a good strong mouthwash, suck on clorets breath fresheners, or buy a spray-on breath freshener from the chemist or alfa alfa tablets to eliminate bad breath, liquorice sweets do the same, or anything with aniseed, or chew on dill, mint or parsley leaves, oh the list is endless, use any herbs you've got handy, they all work in one way or another, oh one last one, eat some hazelnuts. Obviously I dont mean you to do everything I've mentioned, but use some of the ideas.
