Kindle conversion

I've been screwing around with formating for my first book on the kindle.  The whole process is almost shockingly easy, converting word into html then html into a kindle prc file.  The only problem is that in manuscript paragraphs that are totally fine to read now look incredibly bulky on the kindle even at the lower font settings and probably take four or five clicks to get through at the bigger blind old people settings.  Of problems I expected, this one wasn't on the radar, and it's pretty small beans.  If only the perfectionist in me would shut up and go back in his corner.
