Your choices are: shoot a full dose, shoot a partial dose, or skip. This is considered a safe number to shoot, but usually you work your way down with lower and lower preshots, so this is a bit sudden for you. You may want to wait for a better circumstance (all supplies in order, a daytime cycle) to shoot your first under-200 number.
IMPORTANT: That's assuming no history of DKA or ketones-- if Diamond has had a DKA, you want to shoot if at all possible.
If you are feeling up to shooting tonight, it is possible as long as you're ready to monitor and you have something like honey or karo syrup to act as a high-carb booster. If you don't have anything like that, I don't think I would. Almost certainly, Diamond would behave himself and stay in safe numbers if you were to shoot, but it's not worth the risk if you aren't prepared for the alternative.
