I have gone through almost 40 doses in the last 4 days according to the pen with the rubber plunger now at the 260 mark, only 2 doses went into the cat. That means $10 worth of insulin went down the drain in the last 4 days. I have also thrown out about 15 extra syringes, accidentally touched needle, accidentally bent needle taking off cap, along with do overs due to not being able to get bubbles out of syringe. Syringes are cheap, so don’t care so much about those. The problem I am having is when drawing a small dose, I can’t get the air out of the syringe easily, tapping on the barrel is not working when I draw say 1 unit. If I draw out way more than I need, then it is easier to get rid of the air in syringe by tapping barrel. I am trying not to draw out more than a couple of units, but often end up drawing 4 or 5 by accident. Then I try to get it down to .25 and sometimes go too far, so I throw out that syringe and start over. For me getting the right amount of insulin without air in syringe is by far the most difficult thing about this. Thanks for any advice.
