I just got off the phone with MM and they are sending a replacement pump that will be here Monday morning, but in the meantime I have to go back to giving him injections. It's only been 5 months since we've done it but right now my mind is total mush... been messing with this pump for 3 hours! I just checked him and he's 596!!! I can't remember how much humalog to give him or how to figure out how much. I do have his ratio's but he's not going to eat anything for a while. Ok, I need to settle down I know but can someone help me so I can get his level down for now until hubby gets home from work and can take some of this stress.
