It’s been a few months since I started Metformin now.
I would say that overall I’m averaging 108-112 mg/dl. This is about a 5-10 mg/dl drop in my averages from the 3 months prior.
My 90 day average gets a little messed up by a really rough week in the end of February when I was in Italy. My basal needs jumped by 5-6 units and my average bumped up to 122 mg/dl. I think two weeks of pasta and pizza caught up with me
I think my standard deviation is the more impressive statistic. It’s dropped about 5 mg/dl. I’m consistently running a standard deviation of 26-31 mg/dl for each 2 week period. The total standard deviation over the last 90 days is 34 (largely due to that week the end of February).
Contrary to my expectation, my basal needs fluctuate a bit more while on metformin. I’m still working on understanding the variables involved.
Before starting Metformin, I had a 1-2 unit basal need variation depending on the time of the month and activity levels.
Now, I’ll go through times where my basal needs are at 20-21 units/day for a 1-1.5 week-long period, then it’ll jump up to 24 units/day. 24 is still 1 unit lower than my lowest basal needs were prior to starting Metformin, but that’s a HUGE jump from 21 units.
I don’t think it’s entirely attributable to my activity levels (though I suspect they play some role). It may be due to carb intake, but I’m not really sure. I suspect that it’s due to hormones, but the patterns are very different than hormone patterns I’ve previously had. In addition, my prior hormone patterns don’t seem to be occurring - I’m not sure if it’s because they’re obscured by whatever this other variable is or if my basal needs due to hormone levels have changed… if that makes any sense.
Anyway, I’m going to start recording when my basal need changes occur so I can hopefully determine the causes and see how they relate, if at all, to my monthly cycle. If they do relate, I promise to post it on the hormones thread @T1Allison
I still have some nights where I run a little higher, but I respond to my insulin and understand the causes when this occurs. Overall, my evening spikes, when they occur, peak at much lower values because I can control them. It’s still my most challenging time of the day, but I feel like I can control it much more easily.
