What have you tried so far? I would be wary of trying any other substance that can be addictive until I had exhausted other possibilities. Have you also tried to get support for what is underlying the use in the first place? Ending a 10 year relationship that helped you escape some type of pain or another demands that you address whatever that pain is.
It's a journey... it really took me two years to quit. I tried to quit without maintenance initially and failed miserably. Just find what works for you. It gets easier l promise. Good luck
