Is it possible to drink alcohol if I have diabetes?

How much, how often. An occasional drink is generally not harmful to most diabetics, but it depends on how "brittle" their diabetes is. In people who are not well controlled, alcohol will worsen that control. Safe drinking limits in men (2 standard drinks/day) and women and older men (1 drink/day) are not recommended in people with diabetes. You should talk to your doctor, who knows your situation, to get advice.
Yes. As long as you do it in moderation: maximun daily intake: 2 for males, 1 for females (the recommended dose is due to the difference in alcohol metabolism between the males vs. Females.).
