I am 29 and have had type 1 for a year. I got a pump 2 months ago and everything was going OK, but it all of a sudden stopped working (insulin works when injected with syringe, no kinks in tube, remove canula and insulin still comes out, changed sites 5 times.....??) I'm wondering if other pump users have had similar episodes or have any tips for this type of thing. Anyone test out the pump for a while and switch back to shots? I'm about 2 seconds away from doing so. THANKS!
