Trying to conceive and alcohol

My husband and I will start ttc soon and I had a question for you ladies regarding his alcohol consumption.

How strict was your SO with alcohol consumption while ttc?

Like any other person who likes to have a good time on Saturday nights my husband can drink about 12 - 15 units of alcohol on a weekend while we meal prep or while he watches football. He doesn’t drink during the week aside like a beer or two. I rarely drink myself so not drinking will not be a struggle for me.
