Two drinks from my experience that i have to give a 3 unit bolus for each glass is ginger wine which I love at Christmas, and baileys, again only at christmas. Of course it will depend on what carb ratio you use.......
Luckily enough for me a glass of drambuiee or a glass of red wine doesn't raise my levels noticeably.
If I venture beyond this limit I have to give extra...providing I have a glass with dinner and a glass with my tea at Christmas I will be ok....anymore then I have to give extra bolus.......
Everything in moderation though!!
