is there a way to drink plasma for a long time from a sim

@the_sniper_boy94, I don't think the time it takes in game would matter. 🤔 It could take longer, but that wouldn't necessarily mean your Vampire would have more of their thirst quenched.  I would guess that the Deep Drink would be more forceful than the Small Drink.  Most people care more about how filled their Vampire is over how long it take for them to drink.😉

You can look for mods on popular sites for mods , but  beware that Mods and Custom Content (CC) require upkeep to keep them from causing problems in your game.😢  The more you have the more upkeep you will need to do on a regular basis.  I used to use them with other versions of the Sims, but they caused too many problems and I am too lazy to do the upkeep😃.  If you aren't up to the extra work, then I wouldn't advise using them.😞  But if you don't mind the extra work then they can be a lot of fun! 🙂

If you decide to use Mods, then anytime EA releases an update/patch to the game, there is the chance that your mods or CC will become outdated.  If you are having problems you will need to do the following to either rule out a Mods/CC conflict or else to find which Mod or CC item is causing the problem:

1) Move the Mods Folder to your desktop

2) Delete localthumbcache.package file in the game folder.

3) Fix you game in Origin by logging in and go to Library, then right-click on The Sims 4 and choose the "Repair Game" option from the list.  Wait until Origin finishes repairing all your packs and not just the base game.

4) Now, when you turn on your game again, it will create a new mods folder that will be empty.  Check to see if your game is now working without mods/CC.

5) Now you can try adding back items from your Mods folder one at a time checking your game each time to see which item is causing your game to not work properly.  If you have a lot of items, you can try the 50/50 Method. 

The CC creators will usually update the CC items and Mods after these updates, so when you find out which one is the culprit, you can get the updated version from whoever made that item of CC in the first place.  You should try these steps anytime you have problems in your game to rule out CC/Mods problems.  It is the responsibility of the Mods/CC creators to update their items anytime EA releases a patch/update, and it is the responsibility of the people who use Mods/CC to make sure they are using the most recent version. 

I added the above instructions so you can find them later! Happy Simming! 🥳
