have you eaten something different to normal, have you changed your routine, are you stressed or anxious, are you poorly (infection, virus) any of these things and i guess more can have a bearing on your bs, my bs are always high i am on new insulin and they have to be brought down very slowly,but i have been tols by the dn that any of the above can trigger them and the more you worry about it the higher they can go, when you took your quick acting how long ago was it, have you tested for ketones? you can titrate just small amounts every few hours to get these down as long as you keep testing and are aware of what you are doing, but it could also send them the other way if you take too much, insulin lasts about 4hrs on average unless its the 24hr one, so dont take anymore until at least that amount of time has gone past hope this helps
