Yup, the garlic taste and smell is strong. It works best if your spouse/SO eats it too, so they can't complain.
One thing that the Christophers recommend is blending up the garlic with some grapefruit juice and chugging it down. The taste isn't as strong and the odor, at least right at your mouth isn't as strong. It may be worth a try to see how it works for you.
I find that when I do Dr. Schulze 's Liver Flush drink with up to five cloves of garlic, that the odor isn't really very bad. In that drink, you blend the garlic with juice, olive oil, and ginger. I imagine the impact with grapefruit juice would be similar.
