Hi,
I'm starting Uni in October so I'm not the best to spoke of from expeirence however I don't think the experience is far from College. Where I am from, we have two Universities, one caters for the more letters on name and science stuff and the other caters for vocational subjects. My Uni does not have a specific support group although I do have a meeting with a disabilty officer in September to discuss my condition. The other Uni hoever does have a Diabetic Student Union and after speaking with the boss of that, they said that I would be more than welcome as they are catering for both of the Universities. So maybe where you are studying, their maybe a group like that. Other than that it's unlikely you will bump into anyone else who is T1D as it's never something that jumps out at people, it's hard to spot. As for drinking, I drink and before I make sure to eat some carbs, so pasta/pizza as it helps to slow down the drunkening of alcohol. Make sure that if you have any basal insulin such as lantus/levemir to take it before you go out. When you're steaming, the last thing you'll be up for to do is take your night time injection. Oh and don't inject insulin after you begin drinking. The alcohol will at first spike your bloods a little high and then they will lower as alcohol does lower blood sugar. Although its mind altering effects make it a **** insulin. Let me know if my text is a little jaded/hard to read. I type as I talk to mysen.
