TITLE: Drinking an antidepressants -- what can happen from it?
POST: My sister has been going through a lot of stuff. She's left her husband and kids, and won't talk to any of the family except for me, and my brother-in-law when she needs something.

We found out she's taking 4 different prescription drugs a day, two for depression/bipolar, one for headaches, and I forgot what the other was.

The two drugs she's taking for depression are Venlaxfine and Trazodone.

She's been drinking a lot. What started out as a glass of wine a night and some shots on the weekend turned into a bottle of wine a night, a bottle of alcohol every couple of days, mixed in with going to the bar for drinks.

She hasn't been home in a little over a week, so I can't say for sure how much she's drinking, but we know she's been spending $20 almost daily at the liquor store.
TL;DR: 
what can happen from drinking an excessive amount of alcohol while taking antidpressants (Venlafaxine and Trazodone)?
