If you can't get away from it, you can always make your own kifir and then make your own cheese. It's not that difficult. Just pick some granials up from your local health store and follow the instructions and/or ask them how to do it.
If you want to quit dairy altogether, although it's not the same texture, it does have a similar flavour, and if you make it with a home-made veggie dip, it'll be even closer to the real thing, try nutritional yeast. Different from baking yeast, you don't have to worry about yeast issues, and it has a cheesy flavour, and it's really very good for you, even containing B12.
