Yuri,
Welcome aboard. You've come to the right place. Lots of CH'ers here with lots of experience having spent thousands of years collectively in your shoes... They've been there and have the T-shirts, old bottles of ineffective medications to prove it. They will be here to answer your questions so don't be afraid to ask them.
The best thing going as a cluster headache abortive is oxygen therapy. To be really effective, the oxygen flow rate needs to be at least 25 liters/minute. That's a flow rate high enough to support hyperventilation. Sounds wild... but it's not. A flow rate of 25 liters/minute is very safe and very effective with abort times two to three times faster than aborts with a flow rate of 15 liters/minute.
BTW, an Rx for oxygen therapy at 15 liters/minute is about the highest flow rate you'll get prescribed for a while so you're going to need to buy your own 0-25 liter/minute oxygen regulator or better yet, buy one that's capable of 0-60 liters/minute. Again, flow rates this high sound scary but they're not... If you ran up a couple flights of stairs or did jumping jacks for 30 seconds, your level of lung ventilation would be pushing 50 liters/minute and you probably never gave that a second thought...
Many of us have been using the anti-inflammatory regimen as a CH preventative... To date, it's proving to be 75% effective. Many if not all of the CH'ers who've posted favorable responses have gone pain free... It took a few only two days and most two weeks to finally go pain free while taking this regimen.

It will take you to the EFNS guidelines on the treatment of cluster headache and other trigeminal-autonomic cephalalgias. The team of neurologists who prepared these recommendations see more CH'ers in one week than most neurologists see in a lifetime.
