Don't feel guilty. You don't need to put your social life on hold. You could adopt a 2 week on 2 week off approach were you stop drinking during the two week wait. I doubt very much that alcohol is causing any problems. My friends spent about 2 years ttc. They were due to start ivf so thought they'd have a big blowout weekend before sensible diet and drinking for the ivf. Their daughter was conceived that weekend!
I cut out alcohol totally for several months last year out of desperation. It didn't achieve anything other than making me miserable. Given how many people I know were trollied when they conceived, I really struggle to believe that it makes a difference.
That said, I don't drink much these days anyway. All of my friends are sprogged up, so I have no drinking buddies anymore!
