How can Buddhism help with bad habits?

I have been suffering with addictions. Addictions are complex. Both that I suffer from are in abatement. I am in recovery as they say. I am getting medical support. Besides the addiction I have bad habits in relation to being abusive to people when angry. Verbally abusive. Textually abusive. I realise the self is false but it's very hard to shake it off. Before I know it I'm operating from an ego state. Any advice?
