No nap=tantrums

So my son will be three in August. He does not sleep through the night if he has naps like waking up at least three or more times per night. So we stopped giving him naps and have tried that for a few weeks now but he’s just not a fun child to handle after 3/4. What can we do for him to be able to have a nap but also be able to sleep through the night? Or anyone have any other suggestions for me? I’m one tired momma. Tired tired and tired of unnecessary tantrums and screaming until bedtime.
