Drinking alcohol while taking Prozac and Lamotrigine with Bipolar 2

I have bipolar disorder and currently on Prozac 40mg and Lamotrigine 100mg.
I’m planning on going to a Halloween party this weekend, and I’m a little worried. I don’t really drink a lot but the times I do I normally get really drunk, especially drinking liquor.
One time I got so drunk and fell over, someone helped me up and I remember their voices but it was dark and felt like I was kind of dreaming. This only happened for a few minutes
I don’t plan on drinking much, but knowing me I will probably drink more than I need to. I know I will have bad hangover but that’s not what I’m worried about.
Im curious if anyone else drinks on these medications and how it affects them. I take my Prozac in the morning and lamotrigine in the evening around 8. I’m also wondering if I should take my Lamotrigine before drinking or after ?
