DH is a born Jew, so being with him for a few yrs first kind of primed things up. I'd basically been living in a Jewish household, as he kind of kept things going like that and the Rabbi knew him and talked with him quite a lot as well, so he knew what I was experiencing at home. Then it was a yr of Judaism classes for the more "out of the house" learning and enough hebrew for the basics during services as well as regularly going to services and holidays. Then, the beit din and mikveh. But, there is a lot more than just the hoops you have to jump through...
The thing is, Judaism is a life-long sustained effort. And your relationship with it is like any other relationship- it takes making it a priority and takes time to really know it. You will have aspects that will be meaningful and some that will be confusing or frustrating that you will work on. There are things about "being Jewish"- complex feelings of the community about Israel, history, culture- that can only be understood with time and exposure. There are yearly cycles to Judaism that need to be experienced (quite a few times, I'd say... but some of that comes after conversion) before you can really scratch the surface of them. And, even if you will not participate in all the "laws" and traditions, knowing what they are is important. And, the biggest thing is that there is an on-going expectation to be part of the community and an expectation to keep learning after the conversion (really, all Jews are expected to keep learning their whole lives). If you can't get to services and a meeting/class a week (or whatever), it will be hard to be connected afterward. And, afterall, that is the point.
Additionally, becoming a convert to Judaism has some strange curveballs that pop up and the time you will take with the Rabbi and the new community will be important in sorting those out. Your first Christmas season (even if you were not religious before, you are now "different" and will experience being a minority). Explaining things to your family. Finding a peace with being a convert, but not sharing the ethnic heritage or the common memories of born Jews. This Jewish idea of G-d and how it figures into things. How to raise children in a culture and religion that don't hold memories for you personally to use as a basis on which to build emotion and tradition in your home. If your husband is not Jewish, how things will work on a practical level in your house. These things take time and you need to allow yourself to processes them when they happen and they all crop up (for the first time, but not the last!) during the year(s) long conversion study period.
And finally, just focusing on the end result of "the paper" without really being able to allow yourself to wade in and explore is that you will not get to appreciate the "whole package" that doesn't get stuffed into the "classes" or meetings. Some of my most fond and influential memories of that time was reading Shalom Aleichem and getting lost in the richness and fun of Yiddish literature. Of my husband taking me on a "Jewish Tour" of New York City and getting immersed in the art museums and the tennement museum and the flow of the neighborhoods and people, seeing the diversity of Jewish life. Of trying recipes and us having great laughs at my various attempts NOT to "Italianize" them. Of giving a go at discussing the weeks Torah portion and how nervous I was. Of hosting my first Seder. Of having my grandmother-in-law teach me all the Yiddish phrases I was missing. Of flipping through my husband's bar mitzvah album and having long talks with him about his life-long experiences being Jewish, his childhood memories. Going to a funeral. Going to a wedding. Finally getting the jokes. Seeing a random re-run of "Schindlers List" and DH comes home from work to find me a blubbering, crying, having nightmares mess when before, I just remembered watching it and being a sad movie. But now, it's personal. You know. Life. As a Jew. It's more than Friday night

I'm not trying to dissuade you. I'm saying that if you want your piece of paper that says you're Jewish, it is not as "intense" as many might say. The actual "requirements" were not all that consuming. But if you are looking to really see the experience of conversion as a time of learning and soul searching and about understanding the committment you are making and the family you are joining, it takes time. And there is no way around that. But it is a *good* time.
