I had a similar thing happen a few years ago when I went into ketoacidosis. When I woke up that morning, my parents tell me that I was talking to people in the room that weren't there, and when they drove me to the hospital, I am told that I was using my dad's work glove as my cell phone because I was trying to call my friend Matthew...
Then, when we got to the hospital, I don't remember this, but they tell me that I was swearing at my doctors and nurses because they would not give me any water. I remember being thirsty and wanting water, but I must have been really pissed because they tell me that I was swearing (mind you, I don't swear ever, so not like me at all), and I was beating up the doctor so bad that they had to put me in restraints and give me seditives. When I finally came out of it all, my mom said that the same nurses from the ER would come and see me and then comment to her, "She is so nice! You never would have know that from what happened when she came in!" lol

Gotta love diabetes....lol
