If I were in your situation, I'd simply quit. It's not worth it for me to do something I'm not interested in. That's just me though.

For other kinds of jobs where boredom is frequent but where I at least have some free reign to do side projects and develop things for myself, I'll often spend a lot of time writing tools and scripts to automate tasks for myself and my team. That helps get rid of some of the dreariness.
