We all have different response to alcohol, I recall having the perfect reading in the 5's for a week when I visited my relatives in France and hardly touched water- mostly drunk champagne :)
I often have a small glass of wine with dinner with no effect. I have run into trouble when I have got drunk though, twice ,this is the only time ever I needed someone to help me keep blood sugar up, bad if you feel sick and the alcohol is dropping your bgl more.
My husband's friend had a walk around 40 pubs for his 40th birthday and their goal was to have a pint of beer in each pub. Obviously I could not keep up and would not even try as I either fall asleep or get sick as soon as I have had too many (I am not great with beer, can hardly stand after 2 pints). I designed a rota where I had half a pint in the firt pub, a diet coke in the next and a wee in the third, nothing in the next pub and started again and kept up with the party which lasted 2 days!
You can still go out and have posh sparkling water or diet cokes if you are nervous about alcohol, or just slimline tonic and lemon and ice. I still socialized when pregnant although I was totally off alcohol then but did not enjoy it that much when everyone else was having a drink and I was stuck with diet coke.
I would start with a small glass of wine, see if it has much impact on your blood sugar , test once at night if low bedtime but ideally go to bed a bit higher than usual and take it from there. If it plays havoc with your blood sugar, at least you will know why you are not drinking alcohol and your partner will see it too. Most likely, it won't affect you much but everyone is different...
What did you use to enjoy? I hope that all the advice around here will help you regain your social life. It takes some time, though, so do it at your own pace, a lot of us have been around for much longer and took months or years to see what we could do or not with a challenged pancreas.
Maybe your partner is a bit scared by it all and his way of showing it is by pushing you a bit beyond where you feel ready to go? To be honest, when I was pregnant, I was not happy being around merry drunk people while I was sober but this was time limited. What about experimenting at home?
Funny to suggest to you to have a small drink at home, I have worked in a drug and alcohol service as part of my training a few years ago, trying to help people get the motivation to reduce and stop!
With time, things seem to fall into place with less hassle, but it takes time and even then, it can seem a struggle at times.Patronising advice from professionals do not help, even if well meaning.
