Completely agree with the others. Drinking is still possible, but it just needs a little more thinking about, and a degree of caution.
Depending on your tipple of choice, you may find you get a significant upward push on your BGs in the short term (real ales can have approx 20g of carbs per pint). But once the liver gets to work processing them, you are likely to see an overall BG reduction, as it’s too busy to also provide it’s background trickle of glucose.
Any counterregulatory hormone response to low BGs is also likely to be impaired, as will your ability to spot the early signs of an oncoming hypo. Plus as
@Inka says, you’ll potentially have alcohol on your breath and will be behaving in a drunken way because of hypoglycaemia not booze,
The BG-lowering effect of alcohol can be quite dramatic in some people, and can continue through into the following day.
So feel free to enjoy a drink, but be a little cautious, and take some time getting to know how your body responds. Let people know who are with you to keep an eye, take fast acting carbs with you, and carry diabetes medical ID so that if worst comes to worse, the emergency services / paramedics will be alerted.
Alcohol and diabetes can be a tricky subject. Whether you have type 1 or type 2 diabetes, for some people, having a few drinks at home or in the pub is part of everyday life.
