805 - Go for it, regardless. Its a great career, make decent money and you can diversify doing what every you challenge yourself too, narcs, UC, traffic, flying, you name it. In any profession you get jack-offs, just treat people like you want to be treated and it all works out. He who dares wins. Sounds like you have a great job and future, sounds like if you try something else and don't make it, you would all ways have something to fall back on, sounds like you have the motivation to succeed. Marriage issues and alcoholism drug use, etc.. occur everywhere - poor reasons to not try something you want.
Good luck on either route -- Like Yogi said, when there is a fork in the road, take it.
