7-08 my day

Hi everyone, 7-08 God willing is my day at 7 am, for two years I have thought about getting a vasectomy, I have read here and in many places and what scares me the most is the post-vasectomy pain, but I will take the risk anyway, I already have two children and I am 41, I do not want to have any more scares about children, so if you have any advice please, I would appreciate it, and then I will tell you about the experience.
