First DKA since diagnosis

Im type 1 since 2009 and uninsured. Well apparently I tested positive for the flu april 1st and was admitted to the hospital. I was throwing up any fluid. The vomiting wasnt because of the flu but because my sugars were at 850! I was so close to coma. I started going down hill hours after I got into the hospital. My temperature went all the way down to 92. They had to put me in a body warmer thing, it was terrifying. I dont remember alot of it. I ended up in the ICU for 7 days. I was using insulin I was buying at walmart trying to be my own doctor obviously I wasnt doing a good job (using novolin r and n). The hospital left me with a meter and one vial of 70/30 novolog. I ran out of that and now taking 70/30 novolin. My sugars since the hospital have actually been great! Ive been in the 90s and mid 100s and I couldnt be happier about it. I no longer have symptoms of neuropathy and my energy levels have gone up. This disease sucks! but Im so happy that my sugars have been great with cheap novolin from walmart.

Edit: Question. What is the control liquid supposed to be when I test my meter? Is it different for each meter? I did a control test and the meter just says 109.
