Hi all. My husband and I have different opinions on how to draw the insulin regarding exact measurement. I line the plunger up witk the mark I need. So, if I view the needle horizontal, the plunger is flush with the mark. My husband seems to make his doses "fatter". He lines up the plunger just under the mark on syringe. I saw a pic on the internet and this method was used. I need help. My husband has been drawing up the insulin last four days and her BG seemd to be running lower. She will not leave the bathroom. Have no idea what is going on with her.
