Did your SO stop or reduce the amount of alcohol they are drinking while TTC?

I feel like I'm doing everything on my part to help increase my fertility. I've been eating much healthier, taking prenatals and I'm thinking about getting some PreSeed because I noticed I don't get the cm I should be. I mostly stopped drinking. I used to have maybe 2 glasses a night. It was relaxing for me. Now I have 1 every week or 2. I figured a glass here & there should be fine. My husband on the other hand..he's super supportive and definitely wants children but I feel like he doesn't understand that what he does can & does affect his sperm. He won't take vitamins. He won't stop drinking or decrease it. He drinks 4/5 glasses of bourbon and ginger ale each night. He says it's because his job is stressful & it helps him to relax. How do I get through to him? I don't want to be the only one here putting forth effort while he sits back and pretends like what he does doesn't have any affect 😩
