Plenty of support exists for you. The MUFFIN email list is a jewel, and the Feline Diabetes Message Board (FDMB) will connect you with a whole community of people who have diabetic cats and will give you almost immediate feedback. The only thing we have all agreed on entirely is this: trust your own good sense. IF YOU THINK SOMETHING IS NOT RIGHT, TRUST YOUR SELF. A cat's wellness is broadcast by a constellation of behaviors, and the only one who knows him well enough to get the message early is you, who lives with him and cares enough to observe closely and thoughtfully.
