Hi I'm sorry your girl had a bad day, sometimes it can be a case of one step forward two steps back, I hope that it was just a glitch and that she starts to feel better.
Have the vets looked at her teeth? What have they said about them?
Has she ever had them cleaned? wondering if a tooth infection, might be at the root of her problems.
If they haven't mentioned them and you take her in today, ask them directly what they think of her mouth?
When you mentioned the watery eyes, and the pooey mess, I'm just getting flashbacks of George a couple of years ago, he started off being iffy, coat unkempt, dandruff, BG went up from normal (he was in remission at the time) then watery, slitty eyes, then went off his food (he's a very good eater, never says no to food). My regular/local vet run some bloods to the lab, nothing conclusive, so she just wanted to wait and see, wouldn't give me anything, blood tests didn't show signs of infection, but apparently that is not uncommon with teeth infections.
Anyways he got worse even had a couple of mini seizures, and I decided to go for a second opinion to a vet over an hour away who had treated another of my cats for a rather serious gunshot wound. By this point I was suspicious at any rate that it was Georges mouth.
Well the second vet said George had a hideous mouth infection/gingivitis, and wondered why I wasn't giving him AB's, to which I responded 'Other vet said there was nothing to be done, and had refused to give me AB's when I had asked'
Also he asked me why he hadn't had his mouth cleaned ...'Well other vet said the risks of the dental outweighed the benefit to George' To which he said, we either do a dental, or we will loose this cat.
Long and short, George was started on AB's anti inflammatories for pain, then once infection had cleared with the AB's he went in for dental. Had a lot of teeth removed he just has his canines and a couple of molars, but he recovered well from his op and is still with me now, a very senior kitty at the age of 20.
When I nest saw my regular vet, she asked me how George was, I said fine, I took him to see Dr M, and he had a major dental, lots of teeth extracted and now he is fine. To which she replied, well yes his mouth was a mess. I had to bite my tongue, I was so furious, she knew what the problem was but didn't discuss it with me, basically she didn't feel competent to do the dental and have a good outcome so she just didn't tell me he had teeth problems, I would have had much more respect for her had she said to me 'It's his mouth, but I don't want to operate because of x,y,z'
Sorry for the long story, but just wanted to illustrate, that over here, sometimes they might not give you all the information, for fear of upseting you, especially if they feel that there isn't anything they can do to help, and can be reluctant to refer you on to someone that might, for fear of losing your custom.
I use a One Touch Ultra (w/B\GenUltimate strips since genuine One Touch Ultimate strips cats about the same as AlphTrak stripps) strips since for two of my cats. It requires 1uL. In the past I have used a meter that require 3uL. It depends it you cat is a bleeder.
Sure the meter I use is 1ul, but George bleeds sufficiently, and I've had a lot of practice, my friend/petsitter struggles with that so she uses the Freestyle Freedom lite finds that much easier.
A dozen pokes for the pre-shot test and not one of them produced enough of a blood drop.
Have you read the tips on home testing? take a look at the videos on how folk test, I found that watching the videos of different people doing the testing really helped me when I started out. Everyone has a slightly different 'style' so something might just click for you, it did for me when I watched the videos. We all struggle at first.

Here's a link to a picture of the part of the ear you need to try to aim for.

This post by Marje covers a lot of the salient points

What gauge are the needles you are using for the poke? (they come in different sizes if the one your hubby gets fine then that might be the issue) new members usually start with a larger gauge lancet such as 28g or 29g until the ear learns to bleed; then progress to a 31g or 33g which are finer. ( I use a 29, but I have a 28 for my petsitter, again it gives her a bit more blood to play with and that's easier.
Really do the ear warming thing, I use my hands (I always have very warm hands) and I just tickle George and warm his ears with my hands, he loves me messing with them, but you can use a warmed rice sock. I know if I fail to warm Georges ears up, I will not get enough blood for a poke.
