BG Fun and Games

So I’m still having some fun and games with BG but they are getting better!

This is today…

Insulin night before - 22 units Tresiba

Woke up 6am

BG at 6.10am - 11.6

Had a cup of tea.

No insulin (maybe should have for the milk?)

BG at 7.52am - 12.2

Walked to doctors and to collect a parcel

BG at 9.02am - 13.4

BG at 10.42am - 12.0

BG at 13.01pm - 9.6

Insulin - 10 units Novorapid

BG at 15.00pm - 9.0

BG at 16.05pm - 5.3

No snack this afternoon

and no additional insulin.

BG at 16.35pm - 7.0

BG at 17.12pm - 3.8 (meter said 6.0)

7 minutes later Libre reading 5.9

Do you think my sensor is playing up?
Saying I’m hypo and meter saying different.
Numbers jumping drastically.
Last 2 readings drastically different.
