I had a sports gambling problem due to having a serious financial issue pop up around the same time I lost some important people in my life,so I know gambling can be hard to kick and I can really only give you what I did.

I switched from sports to another gamble in poker,which I then turned into Travian and other games online.
The brain just need some kind of kick start to get going down the right path.
I started working out more and lost some weight,which helped me think clearer and not be so quick to look for a way to relieve stress. Now I can gamble without issue and know my limit.

It took a long time to get here and I had 3 months hiccups until I realized I had a 3 month itch. Slowly the waves of itch spaced out and became farther apart. Also letting people know what I was going through helped a lot.
