22 month old won’t sleep. HELP

My 22 month old has never slept through the night. I hate bedtime. It takes an hour plus to put him to bed. Then he wakes up almost every two hours, crying and almost always ends up in our bed or someone in his bed. I’m at my wits end. Is it too late to sleep train? I hate crying it out but at this point, I’ll do whatever I need to do.
