I'm so sorry to hear about your father. The loss of a parent is among life's cruelest situations.

When I first started in AA, it was suggested to me that I shouldn't make any sudden, major changes in the first year of sobriety. I understand, however, that your father's illness provides ample incentive to quit.

Also, when I quit smoking I tallied up how much I spent a month on cigarettes. I smoked a pack a day at $6 a pack. When I did the math I figured out that I was paying $180 a month for my cigs. That $180 a month allowed me to afford a compact car loan. Now, each time I look at my car I picture a carton of cigs with four wheels on it. There's no way I could have afforded the car if I hadn't stopped.

For me, quitting drinking was job one...As my life was a mess & drinking to excess (especially if you're on meds) can worsen your mental health. Whatever you decide, I wish you luck. I'm sorry, again, about your father.
