Alchol before IVF treatment

My husband has planned a surprise trip to Dublin for the weekend for my birthday. Our <a href="">IVF</a> treatment starts 12 weeks from now, 10 weeks after our trip. I've read my notes from the hospital that say I need to avoid drinking alcohol - which I have completely for the past 4 weeks and planned on sticking to until he told me about this trip. Will a weekend of drinking 10 weeks before <a href="">IVF</a> have any effect of its success? Does anyone have any experience of this?
