No judgement from me. It sounds like the drinking is affecting more than just ttc. I don't agree that he shouldn't have to give it up unless a doctor says so. If it upsets you or worries you then that should be enough.
i tend to agree with this. if the constant drinking is impacting your relationship - whether TTC or not - it's time for him to address it. Yes, it might be feeling more like a problem at the moment because you're TTC, but if it's a problem for you guys now, it will become more of a problem when you're pregnant or have a newborn in your home, so it's much better to look at issues now, rather than later kwim?

for us, DH used to be a big drinker. he didn't drink often as he was working away in the truck, but when he was home, he'd have several drinks every night. i know it seemed worse to me than it was, because he was away so much - he was only drinking for a few nights every couple of weeks - but the simple fact he seemed to have to drink EVERY night did my head in! we ended up having a lot of chats about it - the reasons he was drinking, the impact it was having on each of us, what was going to happen when we had a child etc. it was tough going (and i'm kinda glad DH worked away - cos when you're on the phone, you HAVE to talk to each other!)

when DH stopped working away - it got worse for a while. i know it was a self esteem thing. he'd worked his whole life and all of a sudden he was unemployed. so we had a lot of issues - with a three month old baby. it was full on. eventually he made the decision that he wouldn't drink early in the week. it sounds like a token thing, but cutting down on his drinking sun-weds meant he doesn't drink as much the other days - and often will only drink if we have company or he's been doing heavy labour in the yard. he doesn't seem to have that automatic "need" to drink now.

it's really worth having a talk about "now" and "future" and the impact of that drinking habit - and if it gets him to cut back, it can't HURT your TTC chances! if for no other reason than you're more likely to want to DTD if he is making an effort - shagging a guy that reeks of beer when you're sober really isn't that appealling all the time!
