That wouldn't be acceptable for me, at all. I grew up around bad alcoholism, as did DH, so for years and years I had issues with any level of drinking.
Now I'll have a glass or 2 of wine maybe 4 nights a week. DH is a tea totaler. The kids have never seen either of us drunk.
Honestly, with the info you have given, severe binge drinking regularly, getting angry if he can't get drunk, taking sickies to get drunk mid week... it sounds like he has a problem.
A really good guide is asking yourself this - is his drinking impacting negatively on your family, his health, fiances, your marriage? if the answer is yes, then it's pretty safe to say he has a drinking problem and it needs to change.
