I don't want to put you off, but I found my expectation of marked changes didn't happen at all when or how I expected them to.
We're alcoholics and addicts - we're used to instant gratification - doesn't work like that here tho. We have to do the work, and put in the hours, to rebuild a new and better self. Sometimes that means steps or whatever else we're using - and sometimes that just means waiting for mind body and spirit to heal.
They will, so long as you keep your side of the bargain and keep working on yourself and keep sober.
I'm not a very patient guy, but I've gotten better. I've found recovery's a wonderful gift SF - it's worth the wait. I've even learned, from the point I'm at today, to look back at the journey and appreciate it.
good luck
