I have a MM pump and CGM. I went back to the CGM recently after a major low.
I began having (over the last week) lows every night around 2:00am, and then again around 7:00 am. The CGM would alert me, I would treat with 6-8 ounces of apple juice at 2:00. Same at 7:00. The CGM readings were 50-60, as my pump is set to alert me to a low at 60. When I tested at 8 am, I was in the 90-100 range regularly.
Yesterday, I changed my overnight basal from .3 to .275, from midnight to 7:00 am. Between 2:30 am and 7:30 am my CGM readings went from 104 to 182 with a meter reading at 7:30 of 199. That is only an insulin reduction of .175 units over a 7 hour time period.
1. I cannot believe that lowering the basal by .175u could make that much difference and 2. I cannot make any intermediate dosage changes from .3 to .275.
I know I will be asked. I had a normal, low fat, low carb meal at 5:30 and tested at 71 when I went to bed at 10. I did drink about 4 ounces of apple juice, as I hate to go to bed when trending down.
I am flummoxed. Opinions, please!?! Thanks.
