How do you cure a villager multiple times?
Required. Either 1 Splash Potion of Weakness, or 1 Lingering Potion of Weakness if you want to heal multiple zombie villagers, or 1 Arrow of Weakness, or 1 Witch to throw a Splash Potion of Weakness. You can also use a command to give the zombie villager the weakness effect.
If a villager is cured more than once, its discounts increase until the price reaches the minimum of one emerald. As an extra: Villagers around the cured villager are also affected.
These discounts are permanent. If a villager is cured more than once, the discounts get deeper until the price reaches the minimum of one emerald. Villagers near the cured villager are also affected but offer fewer, smaller discounts.
Cured villagers don't give discounts if the player that cured it logs off before the conversion.
You can cure a villager up to five times and get a discount on vanilla.
Normally, a villager being cured multiple times can offer a heavier trading discount than one being cured once. However, when one save & quit the game while a villager is still being cured, upon returning to the game the villager will forget whether it has been cured before.
When you cure a zombie villager, the discounts don't last forever. The more you trade with him the more his prices will get. This is normal, but eventually when you trade a lot with them their prices will not go down and will eventually reset back to the original prices.
Zombie villagers that have been cured and are used to start a new village (player made) never breed, even if given more than enough food/beds. This does not affect naturally spawned/bred villagers.
The final determining factor for trading prices is a player's reputation with a particular village. A positive reputation is gained by curing zombie villagers, though the zombie villager as an individual will offer a much better discount than the rest of the village out of gratitude.
It has recently come to my knowledge that villagers, once cured, do not lower their prices, and, on the contrary, their prices for trades go up. This not only eliminates most late game trading methods involving villagers, it makes a zombified villager a complete waste after being cured.
Do cured villagers restock?
After the villager has been cured they will no longer restock their trades such as paper.
Curing zombie villagers requires throwing a Splash Potion of Weakness at them and then feeding them a golden apple. That villager, and any others that have been cured, will subsequently have much lower prices for their trades than the standard villagers.

Curing zombie villagers can sometimes fail and turns them into illagers. Since illagers seem to villagers that haven't fully recovered from the zombie illness.
When curing a zombie villager, infecting it, and curing it again, the resulting villager has stacked discounts. This exploit makes hero of the village useless (and also allows the fix of MC-153334 to be surpassed with enough curing), as you can just cure villagers multiple times to get the best deals.
Villagers will not restock their trades after their cured from being a zombie villager. and before the zombie villager they were traded with. before the curing the villagers I tested with, they restocked fine. I first encountered it on a server I was playing with friends.
A Nitwit is a villager who has no profession. Once a child grows up after 5 or 6 days it is automatically turned into a nitwit. Nitwits serve no daily functions in your village. They eat your food and produce nothing.
Simple. When the tick speed is higher, baby mobs should grow up faster, and zombie villagers should cure faster.
Villagers become willing to breed when they have either 3 bread, 12 carrots, or 12 potatoes in their inventory.
You could go into Peaceful difficulty and then kill it since it won't be mad anymore. Save this answer. Show activity on this post. TL;DR- Get far away from the golems and they will stop trying to attack you.
You actually can stop your villagers from leaving after telling them they should leave! According to Reddit user u/deenew, if you talk to the villager who is leaving on the same day that they told you they were leaving on a second player profile, you will get the "should I stay?" option again on the second player.
What do I do if I accidentally hit an iron golem?
If you accidentally hit an iron golem that you didn't spawn in an NPC village, you can get him and his cronies to stop being aggro at you by using a potion of invisibility. Even after the effect is gone, the golem(s) should stop attacking you.
Villagers who have been cured by a zombie villager cannot spread gossip.
They are exempt from despawn timers and, barring any bugs (looking at you, Bedrock Edition!), should not despawn on their own. They can, however, be annoyingly hard to keep alive until you get the hang of it. Villagers can die in all sorts of ways.
Breeding. Even though it may feel like they do not do anything, they can still breed like regular villagers. Players can easily create a villager breeder where they use only nitwits for breeding.
Job sites are not required for villagers to breed. The breeding depends on the number of valid beds. If a villager is "willing" (see § Willingness below), villagers breed as long as there are unclaimed beds available within the limits of the village. All baby villagers are initially unemployed.
