How Do You Spend Your Satisfaction Points?

'Steel bladder' is the only one I get that influences their needs. Otherwise they just need to go to the bathroom too often, and it's not like they actually never use the bathroom once they have this trait. After drinking coffee, tea or bar drinks their bladder need still goes down. A lot of Sims get 'Incredibly Friendly' and 'Stoves and Grills Master'. Kids that move out always get the 'Always welcome' trait, so that it actually feels like they're going back home when they visit their parents. I also like to get the 'Re-traiting' potion when it makes sense to me story-wise, e.g. a Sim with the non-committal trait finds their soulmate, then I may change it to romantic or even family-oriented. The rest depends on the Sim I'm playing e.g. 'Gym Rat' for Sims that are into Fitness or Wellness. Some of the potions are really helpful while on vacation in Selvadorada and I really want to push through to the last chest in the temple.
Reward traits I never get are 'Forever Fresh', 'Forever Full', 'Never Weary', 'Needs No One', 'Seldom Sleepy', 'Hardly Hungry' and 'Antiseptic'. And I don't get 'Beguiling' anymore either since it backfired on me once while I was playing another Sim.
