Dr. Lester recommended that we take Dr. North's recommendation and increase methimazole to half tablet (2.5mg of a 5mg tablet) 2x daily and increase sub-q fluids to everyday.

She wants to see him back in two weeks to retest.

He came home, drank a ton of water, and threw it all up.

Looking at his values, most are within range and his hyperthyroid is within range too so why would I increase his dosage? Plus, tests show he's anemic. I'm seeking help online with these issues and will follow up with my vet in two weeks. In the meantime, I ordered some vitamins with iron and am going to order a different type of phosphorus binder and see how all that goes...
