For this reason I'd advise her not to trip without a sober sitter who is acquainted with her diabetes for quite a while until she is used to how psychedelics and confident she can manage her diabetes on her own.
Yeah I'd only suggest a sober sitter if she is a very newly diagnosed diabetic. A newly diagnosed T1 though probably shouldn't be using psychs to begin with, until they get a handle on the disease. I think anyone with a good year or two experience should be fine without a sitter, as long as they recognize the drugs can cause blood sugar levels to go up and down and so they need to be extra careful of themselves.
Of course it doesn't hurt to have everyone around her know of her condition, but generally type 1s don't like to have the mental feeling of being baby sat because of their condition so I would say a sitter is probably a bit much considering shrooms are going to make her think... it would be best to have that be diabetes as little as possible, without forgetting to check her blood sugar of course.

Ok I had another point regarding phenethylamines and stimulants, mostly for IamMe though.
So it can be a bit tricky with these drugs. Generally drugs that increase dopamine (or catecholamine) levels are going to cause blood sugars to raise. Catecholamines stimulate stress hormone release (like cortisol) which can further stimulate glucagon release, hence they can cause your BS to spike rather quickly.
The funny thing though is that excess stimulation in general (whether we are talking a DRI, 5HT agonist or mixed whatever) can also deplete your body of energy (glucose, lipids too even) supplies, and as such you end up with prolonged lows.
I'm not sure what the pharmacology of DOC is, a 5HT agonist I believe. So this is probably on the general stimulation side of things apart from dopamine's effects. But also remember if you're not eating much of any slow digesting food, fasting beforehand, etc combined with the stimulation - it's all a recipe for lows right?
Of course, some of these psychedelics could also have unknown effects on liver glucose metabolism- to slow it down or even turn it off entirely. Insulin sensitivity could also drop during a trip, leading to prolonged lows. There is really a ton of gray area...
