Me too for sometimes wanting to bring my levels down quicker, and then end up overtreating and hypo, but am now getting more used to the idea of not coming down too fast. If it takes 3 hours for it to happen, and it doesn't plummet in to hypoland, then I am happy with that.
With the pump though, I do like to see some movement downward within 30 minutes, just incase it is caused by the pump and gadgets. If I know it is my fault, then I let things be now.
