Since you didn't mention "how" the garlic is prepared when eaten, it may make a difference how it is consumed. I met a patient recently in his eighties and he says he eats garlic every day. I was amazed, I saw this guy on a daily basis for two weeks and I would never have known about the garlic, except that had he told me. I was close enough to change a dressing on his arm, take blood pressure, temp, listen to chest with stethescope. I was in his kitchen during visits to his home, so was there sometimes when he was fixing food. NO SMELL...
He said he takes the whole set of cloves, puts them in the microwave for 30 seconds and when cooled, peels and eats the cloves all day, he described as a "nice buttery flavor and consistency". He gave me a clove to eat and "whallah", no garlic taste or smell. It was wonderful.
Some places I have been, you can smell the garlic through the house and on the breath. I tried cooking garlic cloves in the microwave BEFORE adding to the dish I was preparing and had a totally different flavor/smell than the raw garlic cooking in a pan.
Maybe worth a try.
