Congratulations on the successful surgery. Only thing you can do now is take it easy for a few weeks and listen to your doctors' orders. I don't know of anything you can proactively do to prevent a CSF leak, but I'm sure if you do the stuff they tell your not to do - lift something heavy, sneeze with your mouth shut, push too hard when you are on the potty, etc. - that you can contribute to putting yourself through that complication.
I had a very minor leak when my stitches were first removed 7 days after surgery. In retrospect I think we all rushed the stitch removal because the next day was thanksgiving and I was trying to fly home from LA to Baltimore. Anyway, had to have just 2-3 stitches replaced and then had my head wrapped up for another 36 hours in those horribly uncomfortable pressure bandages.
When I had the stitches removed about a week later back home in Baltimore all was ok (thank goodness).
Good luck on a speedy and complete recovery.
