have quit drinking for 2 months now, still safe to take budeprion?

I am a 26 year old stay at home mother of one. I was diagnosed anxiety when I had open heart surgery two years ago. My 46 year old father recently died 4 months ago of heart failure and I have been diagnosed with anxiety and depression. My heart doctors assures me that I am fine after my surgery but my my mind won't let me believe so. My doctor prescribed me budeprion but I am concerned because I use to be an alcoholic before I had my child (he is 8 months) I drank prob 4 drinks a night for about 2 years. (that was how long I spent debating if I should have the surgery) quit before and after my pregnancy... however i started back after the death of my father. He died a few months after my son was born (my doc thinks this has something to do with my depression too) I am now alcohol free but for about 2 months now but am afraid because it list on the med that if you have suddenly stop drinking don't take because of possible seizures? as you can see, I probably do need the meds but need more info because of my history. thank you.
