I am on **Mirena** and this is an update for the _trends_ that I noticed regarding my insulin needs for **week 1** (and a little bit on week 4) Week 1: - Days **1, 2, and 3** : I am **more insulin sensitive overnight and in the morning**. I used a temp basal of -10% overnight and that _seemed_ to work (without doing any official test but I stayed stable overnight). I found that my morning basal 8AM-11AM was causing me to drift down (whereas normally I stay steady) so I used a temp basal of -20% and that worked great for me. I did not find any other sensitivity at different times of day Week 4: - _I am less convinced of these week 4 trends_ so I’m planning on testing out my theories in a few weeks when I hit week 4 again with better carb and taking notes on what I’m eating - All Week 4 (and possibly week 3): I experienced **insulin resistance associated with meals**. (I did not notice this trend but my CDE did). My basals seemed to be fine over the days and nights (I wasn’t drifting up like I was expecting I would.) However, I consistently experienced **spikes after meals** (meals that I eat frequently and know what amount of insulin normally works for me that I normally do not have spikes for.) - Again, just trends, but next week 3 and 4 I am going to be better about recording what I’m eating and will try adjusting my ICR down so my boluses will be more aggressive for meals --- _[View the full topic](https://forum.fudiabetes.org/t/basal-rates-and-hormones/4133)._
