headaches

I have diagnosed cluster headaches and saw a doctor a year ago but never got to see a neurologist for treatment because my co-pay was ridiculous. Has anyone else suffered wth cluster headaches? And if so what helped you? I get cluster headaches every 2-3 months and they last for 4-5 days at a time, as you can imagine it's very irritating because I have a school/work life and don't have time to "sit out"
