And you'll never be alone on here - there will always be someone around who can help you with any questions you've got and give you support on the days when Chloe drops low (or even just the days when you're finding it all difficult to deal with - those days happen to us all). 
With her +2 being higher than her pre-shot number, it will most probably be another fairly quiet night for Chloe though, like yesterday, a before bed test is a good idea just to make sure - kitties do like to keep us on our toes some days with unexpected numbers! 
And buying Lantus from Marks Marine in Canada is about 1/2 of the price of buying it in the USA - I believe they're somewhere around the $150 mark for a box of 5 pens at the moment, where those same 5 pens here will cost upwards of $400!! I have to say, much of the credit for that goes to the people here who welcomed me when I first joined, answered all my questions no matter how small they were, and were there for me on the days when Rosa was dropping low and I needed support or when I wasn't sure what to do next with her dose - I really don't think I could have kept up with the protocol without this board!
LOL - Eat, sleep, and eat some more, lol. I am giving her just the Purina DM wet and adding some water like @rhiannon and shadow suggested. That seems to be helping it stay nicer longer!
She's definitely doing well today - no real lows and nothing too horribly high either.
The Tight Regulation protocol can be tiring at times - I'm not going to lie to you about that. There are days when they look like they might head low when you might have to get a couple of tests in overnight. But it does give you the best possible chance of getting a cat OTJ - and remember, if Chloe doesn't head in the direction of OTJ and you want to switch to the Start Low Go Slow protocol sometime in the future, you can still do that too.
Walmart sell syringes with 1/2 unit markings - as far as I know, all their 3/10 cc syringes come with the 1/2 unit markings (though the pharmacy staff don't always know that).
I had Rosa on Tight Regulation (with more testing than is strictly necessary as she did like to dive on occasion, so I could never be sure that she wouldn't pull a sneaky fast drop on me if I wasn't paying attention). She did respond better to the protocol than I could ever have hoped for given her dreadful numbers for the first couple of weeks and, although I did have days where it was tough going and days where I doubted what I was doing, it did definitely work for her in the end.
) I can't thank you all enough!
The Lantus pens are a direct alternative to the vial - it just means that, especially with a cat on a fairly low dose like Chloe is at the moment, you should be able to use up all the insulin in the pen before it stops being as effective as the pens contain 300 units each and come in a box of 5 where the vial is 1000 units which is difficult to use before the 6 months is up unless a cat is on a high dose! Your vet will be able to prescribe the pens instead of the vial, but you might have to ask them to do it that way - my vet prescribed the vial and I didn't know any better at the time and paid almost $300 for it at Costco. Though I was able to pass about 2/3 of it on to someone else whose cat is on a higher dose, so at least I didn't have to throw the rest of it in the trash.
Thank you all for your continued support and help!
If you were lucky with it, it might last longer than 6 months but most people here seem to find it stops being as effective around then. Your vet might not have known - it's not always easy to be certain...the manufacturer says 28 days, a lot of vets say 3 months, but people here have found that up to 6 months is possible. If you're still using that original vial and it's clearly still working, then that's fine - you can keep using it. If you can get a prescription for the pens anyway, you can still go ahead and order those (unopened they're good until the expiry date) and that way if you find her numbers start rising, you'd have new insulin to use without having to wait for delivery of it.
So, I'm working/surfing to stay awake. lol
You can always work on adjusting her shot time back starting tomorrow - and you will still have the option of doing an 18 hour cycle at some point or skipping a shot if she's low enough to get back on track.
Of course you can always post asking for advice if you get a low preshot - that way you'll know if there's someone who can be available until after her nadir in case you need some moral support if you decide to shoot a lower number.
So, if she's below 150 and I can't be around to watch her, then I should skip, but if I want to get on better hours, and she's in the 200's, going 18hours might be ok? I'm going to go snooze and I'll be back in 2 hours to give her a dose. Thanks again!!! 
And then try and get a least a couple of hours sleep before you test again - no point killing yourself to stay awake when she's unlikely to drop very low in the next 2 hours.
