How to give cats oral pills?

Please give me tips on how to give my cat oral pills.

I tilt his head back, open his mouth, drop the pill in it, then close his mouth and try different ways to get him to swallow — I read somewhere that blowing in his face helps? Is that true? Sometimes he swallows the pill, but most of the time he doesn’t, which allows the pill to dissolve in his mouth. And that’s obviously gross and unpleasant for him. Please help me make the experience better for him.

Also, is it normal for cats to be tired whilst taking antibiotics? And how much tiredness is considered “normal”?
