I hate to be that guy again, but: If you're asking that question, you definitely shouldn't be playing 200NL. Start with a stake where it doesn't hurt you to loose 50BI and build a roll there.
There is not a single FTR success story that goes like: I have never played poker, but I took a shot at midstakes and here I am!
Not since 2005 at least.
There are however quite a lot that started with the lowest stakes possible.
