Hi Rachy, hope you are feeling a bit better! Would I be guessing right at hangover perhaps? My son, 16 years and recently T1 diagnosed, had a 'serious' talking to by diabetes doctor this week. Basically, if you have alcohol and feel rough in the morning please get yourself to the diabetes team - they wont judge, she said it happens all the time and it's their "bread and butter" but the message was to let them help before you get ill. If you are still feeling rough and throwing up then please do get in touch with you diabetes team. Al the best!
