While I would hope this is intended to be humour suggesting whiskey to a 16 year old seeking advice on diabetic management on an Internet forum, where you cannot ensure to "joke" of your message is conveyed in the delivery, is, at best, unwise.
How to you manage your diabetes
@t1caitlin ? Do you pump? If so you could look at using an increased temporary basal rate for stressful days, or set an exam day basal rate. You'd have to do it cautiously because there's no guarantee you'll be stressed (it's possible, it might all go smoothly and you'll be super calm) or that the exam stress will increase blood sugar. If you're on mdi what kind of basal are you on?
JDRF has good information on diabetic preparations for exams - making sure you have access to monitors, hypo treatments etc -
