Hello,
Do you find yourself treating hypos, or possibly snacking to pre-empt & avoid lows with what you do.? (Day to day & the dance teaching.)
Healthy BG levels are paramount, (easier said than done.) if the above is what you seem to be doing to avoid lows?
The start (with consultation with your HCPs.) would be basal testing. Before focusing on what you bolus for with your personal choice your diet.
I hope this helps? As a T1 active man (myself.) expecting a little "middle aged spread," it never happened to date..
I sort of tripped over my balance by accident. & it can be bewildering when things change.
Are you using a CGM like a Libre? To monitor your trends? This can also be a useful tool.
Best wishes finding your "you.."
