Hi Kristina,
I'm very sorry to hear that Brady is not eating. If he's refusing all food then you need to get that addressed urgently. If he's heaving like that then there's definitely something up - it doesn't sound like ordinary nausea.
I strongly recommend that you get Brady back to the vet as soon as possible. As you've not given insulin and he's not eating and really poorly there is an increased risk of diabetic ketoacidosis (DKA - potentially life-threatening) you need to get the vet to test straight away for ketones. Also ask the vet if they can do a SNAP fPL test today in case it might be pancreatitis (it can cause diarrhoea, vomiting and inappetence). If the vet can do the test in-house you'd get a yes/no answer as to likelihood of its presence. Also, if he were mine I'd ask the vet if Brady might have ingested something to cause this.
If it is pancreatitis, things that can help are:
Cerenia - for nausea and vomiting
Ondansetron - for nausea
Famotidine - for stomach acid
Buprenorphine - for pain
Cyproheptadine - for appetite stimulation (need to give stuff for nausea before this - check with vet about Brady's liver status). Gentler than mirtazapine, doesn't last as long so easier to control dosing.
Mirtazapine - alternative appetite stimulant (WARNING: can cause serotonin syndrome - may interact with buprenorphine and ondansetron- 1/8 of a 15mg tablet can take 3 days to clear system - antidote is cyproheptadine)
Flaygyl - for diarrhoea - tastes foul. Active ingredient is antibiotic metronidazole. Saoirse was given Stomorgyl 2 which contains metronidazole & another antibiotic - apparently not as foul-tasting.
Kaolin paste with probiotic - for diarrhoea (e.g. Pro-Kolin).
Bland food - e.g home poached chicken - mince up finely and give c 1 tbsp every hour with some water and some of the broth from the poaching. Keep to tiny meals for a good while, even if Brady would eat more at a sitting it is easier on the digestive system to give small amounts at a time. (If you're home nursing, timed feeders are a godsend.)
Fluids - ask vet about sub-qs.
