Hi
@Levy - Sadly this is the joy of living with type 1..
Just when you think you have it sorted a curve ball comes along and throws everything haywire. I too have seen changes with no rhyme or reason over the past few weeks, some great and some dreadful. The only thing I can say is to just try and stick with it for a few more days to get some regular patterns in and seeing what the outcome is, I wouldn't rush into basal changes though as there are bugs about and this could be a possible reason so maybe just keep a watchful eye over the next few days and correct where necessary, rather than adjusting your basal just yet.
