Meds and bud

So for awhile, I have been wanting to get help for anxiety and depression rather than just smoking to deal with it. I want smoking to be something I do only to enjoy myself, not something I do to mask my emotions. So here's my question..

Is it wrong to only smoke at night? Like will it still interact with my meds? I'm gonna be taking Gabbapentin and Zoloft. I've been wanting to cut back on my use anyways. Should my meds still work fine if I smoke only once a night? Or do I need to cut back more to get the full effects of my medication?
