I am just wondering because I have tried as much as 15 ius of HUmulin ( cant get humalog) post workout and my bg levels never dropped. I have monitored my bg levels for a week at different times of the day to get an accurate reading. I am assuming i should increase the insulin since ti having no effects on my bg levels. Also, my avg bg level is 73, does that low level have anything to do with me not responding?
