If you're an Orthodox, Sigdet definitely helps. Also if you can talk to a nefs Abat.
Other than that, avoid being idol, make yourself busy. And don't lay on your bed unless you're worn out and young want to sleep. Avoid, as much as possible touching your down areas.
Always keep in your mind that masturbation is huge a sin, and it, not only messes up your relationship with God but also ruins you mentally. Btw, once in a month means you've not yet reached an addictive level. Stop now when you can.
Also, don't procrastinate, start today. Don't say, "beka next time", "Kezare jemero", "Lemecheresha gize", the last time you masturbated should now be the last time EVER you masturbate. Believe me, once you stop, you'll watch yourself change, thrive mentally & spirituality.
The best cure for it is Nesseha, Nisseha is not only important but, a must. Once you repent to your nefs Abat and get that weight off your shoulders, it's going to be hard for your desires to control you. At least, you'll fear going back to mud after you get yourself cleaned right?
I hope this helped, Emebete tirdash.
