Love my T:slim BUT

I'm having a hard time with getting the insulin to restart after I change a cartridge. I've spoken with the customer support folks, my Endo, and the pump instructor, and no one can seem to figure it out.

Anyone having similar issues?

As in the insulin gauge isn't resetting or the pump won't resume pumping out insulin after the change?

The later. The pump takes forever to get going. Sometimes I have to give myself up to 10 unjustified units just to get any action out of the pump.

So it primes all the way and resumes insulin, but you seem to have to bolus 10u to keep from going high? After a set change?
