I can't exactly remember as it was so long ago but I'm going to guess I was drinking more than that, maybe 3-4 times per week, how much each time I honestly can't say but usually once I started I didn't stop until I went to bed so probably close to a bottle of wine each time.
I do distinctly remember that I'd gone out and partied the weekend before I took the prego test and gotten completely wasted....that scared the crap out of me more than anything else but all was well in the end.
