Mod to slow down motives/need decay?

[dewmongo]

is there a cheat or a mod that slows down the decay of needs/motives? i used to use the cheat testingcheats.true then shift and click on the mailbox, and stopped the decrease of needs all together. but that takes some of the fun out of the game. however,  when i dont use that cheat my sims needs go down really fast that i have no time to do anthing except try to bring them back up.

i want the needs to decrease but not at such a fast rate. are there any current mods? all the ones i found are outdated.
