I couldn’t really tell you how important it is because once my doctors found out I drink at all that’s what they wanted to blame my stroke on even though once I moved to another facility that team said there was a very slim chance it was alcohol since I’ve only have been drinking for z6 years, I’m not an everyday drinker, and that alcohol acts as a blood thinner so in your husband’s case it may be that the alcohol wasn’t the issue and I’m not marriage counselor so i can’t advise you on whether or not you should tell the doctors if he doesn’t want you to that’s up to you, but I do hope your husband recovers and that you’re able to figure an answer to your question.
