Got it! Next time, if you get a number you're not comfortable with at shot time, don't feed and post for help. We want to see if Ruddy's numbers are going up on their own. Especially since we don't have data on what he did during the day. Did you take a test during the day and perhaps didn't input it in the SS yet?
For now, you have a couple of options:
1. shoot the regular dose. But you'll have to be prepared to monitor. I understand you said you can't be up all night though.
2. shoot a reduced dose. How much is up to you.
Personally, I would try my best to shoot the regular dose. The saying is to shoot low to stay low. Yesterday, you shot a 7.5 which isn't too far off from 6.7. If you can decide if you can monitor throughout the night (perhaps set up alarms and sleep in between tests), then I'd go with that option.
Either way, after you give insulin, grab a +1 and +2 test.
Great that you have an autofeeder! I'd load up with food regardless of what dose you decide to shoot tonight.
