about the blood sugar: Possibly. I have chronic low blood sugar (11 years), and have gotten to the point of slurring words... but very few times. but once you reach that point you are seconds away from blacking out. it may affect people differently, but when my blood sugar drops the symptoms are always the same...first i get very hot and begin to sweat, then naseau, then black out. But if it is low blood sugar, sugar pills or food should work right away. if she is not blacking out directly after slurring her words, i find it hard to believe that it is low blood sugar. and i have no idea about the glassy eyes. also, if she was having blood sugar episodes, they wouldn't just appear when she was under stress.
the obvious would be that she is drinking again, but it could have something to do with blood PRESSURE if she is not drinking. very high blood pressure can cause both those symptoms - it recently happened to my mother in law - slurred words, glassy eyes, and flushness.....which are symptoms of a stroke. if you honestly believe she is not drinking, she needs to see a dr.
could SAD alone cause those symptoms? i don't know, but i am sure someone does. good luck to her. and you.
