Hi
@jimmysmith ,
If you are relatively new to this then you may still be producing some of your own insulin and the production of it could be sporadic. This is often referred to as the
Honeymoon Period. It can come at times when you don't expect it and mean that you have extra insulin flowing around inside you. (Did you eat anything that might trigger insulin production?)
If this is the reason (and it may not be), it can last a few weeks and in a few cases up to a year or more. I'm afraid we always need to watch out for the odd curveball - even when you've been doing it a while.
Temperature may have an effect also - as when we are warm, our bodies generally absorb insulin more efficiently. Is there any chance you did things in a different order - like injecting straight after a shower/bath?
