Here are some of the strategies I have used and worked.
First, do NOT go out without preparation. I usually have some high fat item to eat to coat the stomach a bit. Deviled egg, a few meatballs, cubed cheese, that sort of thing. The first drink I have is rum or brandy with a splash of double cream. After that, I can handle a couple of straight drinks, nothing with mixes, just straight up or on the rocks. That is the lowest in carbs.
Not for the reality check. The lower your average carbs are, the less likely you can handle hard booze. The body does not digest alcohol, it goes straight into the blood stream. Yet, for some odd reason, it thinks it is sugar. I don't understand the mechanism (may be worth a search and read) but I do know that I am certainly less tolerant the longer and lower carb I am. I mean it can be as bad as 2 drinks knock me like 4 or 5 would have when I was eating high carb.
So do be careful and find your personal tolerance. Plain, straight booze is the lowest in carbs. But don't let that be your sole guide. Deep dry red wines are also low in carbs, that may be a better option. Alternating a drink with club soda or water is an excellent way to stay hydrated and space the drink out.
Have fun and remember, this is YOUR journey, find what works for YOU!
