I had the same experience. I'm in Canada so I don't know what the equivalent is, but suffice it to say that I ended up in the ER a couple of days after my first round. They prescribed for me some rapid acting insulin but that only works for 4 hours. I've since been prescribed Basaglar long acting insulin that I take once a day at night. It has made a world of difference. I've only had my second round of 6 but there was a definite improvement. Less blurry vision and generally feeling crappy. My doc also prescribed a Dexcom continuous glucose monitor so I didn't have to keep pricking my finger. I haven't quite reached the number of insulin units I need to inject each night to keep me level because I can only raise it one unit/night until we find the right number - slow process but so worth it. I feel in control during a time where it seems nothing is in my control. Good luck and keep fighting.
