Prime is the new one.
I test, feed and shoot, in that order, within about 5 minutes. If he doesn't have spit-up issues, you should be able to do that. I don't usually feed within 2 hours before shot time. But if you give him something, keep it small. Some people say to feed early in the cycle and then nothing til the next shot time. Others every 6 hours. You'll get the best advice on the Insulin board for Lantus - they've got many more eyes and LOTS more experience than me. Also, because of Grayson's Acromegaly, he's been like a teenage boy,
Also keep in mind that if you get too big of a drop of blood, or if it is too little, you can get a "wonky" reading. Take your time when you're testing to ensure you're consistent from one test to the next. And don't let yourself be interupted. No phone, no anything else. I've messed up a couple of times... actually did everything BUT shoot, cuz I was distracted!
Some folks here have had problems with meters named True... my first meter was from Walgreens, and it was a true something... I ran simultaneous tests with Kim's Accu Chek, and we were off by a few points - and then over a hundred. The ReliOn Confirm (also Arkray) has to have the strips pushed in a little harder as well, but seems to give fairly consistent readings. If you want to look at my spreadsheet, you can see the xxx.xxx readings under another reading. The top is my Accu-Chek Aviva; the left one is the Bayer Contour, and the right one is the ReliOn Confirm. The Bayer is about to be discontinued, so I'm doing meter testing for DCIN (Diabetic Cats in Need) for their fosters to use, and we needed to see how accurate/consistent it is. Just don't freak out when you see Grayson's doses, as I said yesterday, he's insulin-resistent, so it's HUGE< and definitely not something anyone else should do!
