I’m an expert

although not really on beer. I agree if just a pint, then a full bolus but none for dry white, red and half bolus for sweet white and Prosecco.
I used to do this with alcopops, cocktails, Prosecco and beer. When I’m in Spain I drink beer but with heat I only take insulin for first beer and if only one then half plus they are smaller there. I hate the extra phaff of insulin with alcohol so I now drink gin and used to drink red wine with no bolus insulin at all.
For anyone else reading, doctors, for most of my life, told me to eat tons before bed which i always did to avoid night hypos and reduce basal -which I hear is due to the common night hypos - but they never believed me that I’d always end up very high all night. Thanks to CGM they believe me now and I know that it was not the right advice for me personally.
I now drink alcohol that doesn’t require a bolus, no carbs or reduction but I need to accept its highly likely that hangover time (9-11am) my insulin will be super sensitive for breakfast so then I need to reduce insulin only when I eat and expect hypos around this time.
