You would probably have been better drinking the wine and cutting out the beer , particularly if wine if dry white or red which are both of which are lower carb than beer. Many spirits are low or nil carb , but of course high in alcohol and mixers will increase the carb intake . I also understand that there can be an interaction of alcohol and some diabetic medicines - so read the instructions and limitations about alcohol.
Everyone reacts differently to carbs so is trial and error and you need to test to see what you can tolerate. In my case I cut out sugar, potatoes, bread and all grains so no breakfast cereals , oats ( although some can tolerate) , no pasta, rice or most fruits apart from berries although the occasional apple , pear may be OK. Vegetables and salads are above ground but some find peas not a good idea but they are fine for me . Cheese , meat , ( I do not eat fish as allergic but it is fine indeed good for others ) all OK in moderation - aim for 0.8 protein per kilo of the weight you want to be ( if wanting to loose weight). Low fat foods often have sugar in them so full fat yogurt, butter, cream, olive oil is better. For snacks hand full of nuts ( no more than say 5 Brazil nuts ), stick of cheese, olives , pork crackling are all low carb occasional treat 85% chocolate two pieces. Drink at least 1.5 to 2 litres of fluid a day ( milk has sugar in it so can cause issues ) and diet drinks can have odd reactions ( diet coke makes me hungry I tend to have as an occasional treat).
On this forum you can see a section about low carb diets which have a lot more detail .
I suspect others will be along with more information
