i think everyone is nervous about shooting low numbers. don't worry about hesitating - it's not a race.
the key thing in all of this, shooting any numbers, is that you want to be available and ready if they go low. you always need to have a stash of test strips, realistically probably at least 15 extra strips & lancets, to be able to get through a low number event. when you get your next supply, might be a good idea to set aside a few - they have to be shut in their container, of course, i just mean mentally.
it helped me to understand how lantus works. when you inject the liquid in, it forms a micro-crystalline deposit under the skin. then that deposit, what we call a shed, dissipates slowly - which is what evens out the BG numbers compared to other insulins.
it also helped me to learn that just because a cat might drop from 300 to 200 on a dose doesn't mean that they will drop from 100 to 0 on the same dose. for whatever reason, the drops from the higher numbers are often more rapid than drops from lower numbers. every cat is different, and as you test milo, you are learning how milo's body works on the insulin.
