Welcome peanutbutter (would love to know the story behind you choosing that name!) So glad to hear you have begun exploring meditation and mindfulness. I think everyone's path is very individual, so it's hard to say when you will 'feel' like it is benefiting you, but with time I am certain you will. I think it can sometimes be detrimental to think in terms of what is 'typical' or to be too focused on when or how, because then your own expectations can get in the way, and keep you from seeing what is right there already.
That being said, I think one of the first benefits that many people see is a shift in their relationship to their own thoughts. You mention feeling like you are stuck in routine, just going through the motions. I think if you begin to think of your mindfulness practice as something you attempt all the time, not just when you 'sit down' to meditate, you will see a shift right away in that regard. You will start to feel more alive more often.
There are a lot of wise people in the BellaOnline forums, on all sorts of different kinds of spiritual paths, so I do hope more chime in! Good luck-
