Try eating garlic in its natural form. Use a peeler, grate it up, cover it in honey and just swallow. I take in two cloves a day this way. I do a soy milk chaser if I think I will taste it. No stink breath. No problems. Took about 10 days steady and the shedding stopped. Now, it's a habit. The pills have so little allicin and sulfur, it is just a waste of cash.
I am not sure what would happen if you sleep in it, but in coconut oil I don't think it would be bad...
