Always and I do mean ALWAYS pack extra supplies. Today could have turned out so much worse had I not had an extra Rx on file for Humalog Quick Pens I would have had to wait nearly 30 minutes for any insulin at all. I was changing the cartridge on the T:Slim and for some reason which was most likely human error the pump would not accept the new cartridge so we (my husband and myself) were stuck with no way to get insulin into me and we needed to fix a high of 300 (site gave out prior to change). Needless to say had we just had extra supplies everything would have turned out well. Note to Self and all other Pumpers... Pack twice as much as you think you need because you never know when something will break.
Keep on pumping,
