couple of thoughts -- if it's late in the cycle and he's hungry, get out some freeze dry treats or some non-fatty chicken, the protein-only treat may not affect the BG that much -- when Catcat gets miserable about "mom I'm hungry" I break out the bonito curls
syringes -- and bubble -- have been getting a rash of those lately -- I've found that if you depress the plunger as hard as you can and hold it in while you are piercing the vial, then let it go after that, you get smaller bubbles -- with Vetsulin, the way the vet had me shake it vigorously, the real bubble problem was getting them to quit being froth on top of the liquid in the vial -- sometimes I'd have to flick it or roll it for as much as ten minutes before it dissipated
the Relion syringes are a frustration since when you do get the bubble up to the top, it's still at the side of the syringe, not centered, and it won't just go out when you try to expel it, you have to pull plunger back to get more air in the barrel, then flick it to get all the air up to the top to eject it
