Another question about kefir: causes congestion

I just tried kefir last weekend and I LOVED it! I love that tart taste. However, I eat no dairy because it causes me to make too much mucus... And, after I ate a quart of kefir over the course of a few days, I became seriously congested. I did find some soy kefir, but it was flavored and sweetened like a smoothie kind of thing and from what I read on this forum, soy isn't too good for you anyway ( altho I do drink some soy milk.) So should I try to find plain soy kefir? Or will digestive enzymes keep the milk kefir from making me mucus-y? I'm really not up for making my own right now ! :) And BTW, what IS your opinion of soy products?

Also, I used some in an enema --is that something I need to do more than once to get good results?
