Insulin not working

Sometimes approx 2 to 3 times a week I find that my insulin has not worked it can be at any time of day I know I have given it and it just has had no effect on reducing my bood sugars.

Can you check your injection sites. It may be that your skin is a bit lumpy in places and this is hindering your insulin absorbtion.
Keep track of your injection sites using your online diary, keeping accurate notes about position in the comments and it could help you discover a causal link.
I find that I have to carefully rotate my injection sites in order to avoid the same symptoms you describe.

Thank you Garry will do that

Obviously you need to check expiry date and other things like what temperature it is kept at and is pen working ok.

Good points.
And A Happy New Year to us all.
