I'm another 6 average too and feel your pain. Use the libre to look at how quickly you recover from a raise, if its straight up and down with an hour that's better than a prolonged raise or one that lowers only slowly over hours.
I find my bg goes up when I have a shower but is back to normal by the time I've dried my hair. I'm not going to stop showering, it's part of normal life.
Your probably having quick ups and downs.
Look too at the time in range, I bet you'll be surprised at high that is
Imho carb vigilance is going to be lifelong, but without it your average would be soooo much worse, and leading to complications.
7 years in is a huge success. It can't have been easy starting lc back then. You've got through those difficult first hurdles it's just fine tuning now, and watching out for any changes.
You've got this!
