welcome Fenway;
For me, alcohol fuels my depression which makes me want to drink which makes me more depressed....As I have stopped drinking for 13 days, one thing I noticed is that I am NOT as depressed, my mood is considerably lighter...I am not on meds at this time, i have taken Zoloft in the past, it did not agree with me...(perhaps because I drank too much while taking it)
No one can tell you when to stop except yourself, but the reason you came here is the right direction.
