Well, I just have to applaud both of you (Slick and Mary) on giving fluids by yourself. There's no way I could have done Taz's alone. I would have taken him to the vet every other day if Bruce wasn't here.
Did they show you to gently massage the area where the fluid is going in to help the flow go better? At least I think that's what it did. I did that, but sometimes that would make him jumpy. I think maybe because I'd rub too close to the needle.

I'm still hoping he gets better soon.
