Well technically, you shoot the drop! Chances are good she will surf along in green numbers and be a good girl. Then there's you, the Bean, who won't want to trust that's what she will do, SO ultimately, it's up to you. Are you up for testing for a few hours to confirm she is staying safe or do you need some rest? Do you have plenty of supplies on hand on the off chance you need them? That said, she was at 50 earlier and that could have been a little below or above 50. I don't think there is a right or wrong answer here. If you need some rest after the last few nights, I'd skip and see how she does without her drop dose. Other than those blue pre-shots in the AM, she's looking excellent! The nice thing about Lantus is that you can shoot low numbers and they usually just surf along beautifully.
