husband drinking

Almost 5 months pregnant and the hubs like to do shots and drink all day when he is in the presence of certain ppl. When I bring it up about me not wanting him to get drunk he just blows it off and makes it out to be like I don't want him to have fun since I can't. I just don't like being the Lone Ranger while he's cutting up and being a different person. How do I approach him about not drinking at all while I can't or about just having a few drinks to socialize then stopping not drinking 8 or 9 and doing shots?
