Tackling Addictions Directly VS Meditation

I gathered some ideas from different previous replies, but I thought I'd synthesize these ideas into a question. Is it (1) more sensible to cut down on addictive behaviours *in order to* liberate one's time for meditation, or (2) meditate despite addictive behaviours present *as to* cause their diminution. In other words, will addictive behaviours diminish naturally from a meditation practice? Or, will diminishing addictions and procrastination and such enable meditation? Personally, I feel my attempts at diminishing attachments have generated very few effortful and beneficial behaviours. It seems the other way around: meditation, exercise, reading all *lead* to more efficient time-spending. If this is so, then it seems to imply diminishing *all* attachments is less beneficial than tackling gross aversion to effort. Any thoughts? Thank you. (Extra thought: can we say expending effort involves a process of *becoming*, given there's an investment producing effects? In this sense, effortful activities like those I mention have a karmic -- i.e. efficient -- effect, while detachment involves removing oneself from karma. For example, I could exercise and produce a good result, but by avoiding junk food I am *avoiding* negative consequences. Just a thought!)
