After having our second kid and my wife not wanting to have additional surgery (two C-Sections and a few abdominal surgeries) I decided to get the snip because, while I love our kids, being a parent is a big job and I didn't want any "happy accidents" later in life.
So, one call and one visit to the dr and I've got the surgery schedule. I decided to have the local anesthic (sp?) because I wanted to drive home immediately. So I was awake for the whole thing; it's a cake walk. It took less than 20 mins start to finish, the only pain was the injection of lanacane (again sp?) but it wasn't bad. No pain aftewards. I made sure the equipments still worked that night with a self test.
One thing to consider, which I didn't know going in, you're not immediately sterile after the procedure. It takes about 2 monts for all the boys to make their way out so use protection until you have your count confrimed to be zero (they give you a kit to take samples in a few weeks after the deal goes down).
