I’m about to get into Gravity’s Rainbow and I’m a bit nervous

I like to think I'm at least a good reader (I read The Bleeding Edge no problem and I made my way through Blood Meridian) but this book seems extremely daunting. It's quite lobg and everyone ive heard about this book from seems to say it is impossible to uderstand at any point. I really want to read this but am worried I am not ready. I'm also not one to reread books which worries me cause it seems to be necessary for this book. Is there any advice you can give to me before I get into it? Should I even try?
