All of this. As an adult with T1, I don't really drink often, and if I do, it's rarely more than a drink or two. It's really just too complicated to deal with more than that, more often (and that's aside from the issues of having 3 kids and being an otherwise responsible adult). I've come to that decision by trial and error, basically it's not worth the risk of scary lows (and it's CRUCIAL for every T1 to know that glucagon WILL NOT work with alcohol in your system, the liver prioritizes processing alcohol above all else, and the liver is what responds to glucagon), or dealing with highs from mixed drinks without feeling comfortable aggressively bolusing/correcting. Not all adults with T1 will come to that conclusion, and I will admit that I did drink a lot more before I had T1 (and yeah, not legally, and I was only 16/17 and my parents did not know) so in some ways I am lucky that I "got it out of my system" before I had more to worry about, so I really was NOT drinking by the time I got to college.. at least not with the typical college crowd (even before I had a kid, was married, etc, I didn't really "fit in" with most people my age in school, which limited my opportunities to do stupid things at that point). I have only gotten really really drunk once as an adult with T1, and it was with my dad, who I think was scared by the whole experience more than he expected he would be (I was 23 or 24 at the time, so 3 or 4 years after my diagnosis, and it was the last time I've been that drunk). I was not in the best place emotionally... I had recently "quit" college for good (knowing I probably wouldn't go back), I had been fighting with my husband about a number of things (which have since been resolved, thankfully), and I got out of town for the weekend to visit my dad and his family just to breathe a bit, and my dad took me out to blow off some steam... it didn't end well for me (I puked in the parking lot, and in the yard at my dad's house, and my BG was in the upper 200's and low 300's and stayed there all night, and no, I didn't end up in DKA), but it could have been worse. I will say this... as the parent of a 15 year old, the thought of him doing the same idiotic things I did as a teenager scares the crap out of me, and that is without T1 in the mix for him. My heart really goes out to anyone in this situation, and I wish I had better advice to give.
