I use relativity to make my days a bit longer. I also use the relative motives so that my sims dont have to sleep twice a day. However, while it does reduce decay (I might be wrong on this) it kinda feels like it doesn’t reduce the energy gain from sleeping. My sim is sleeping in one of the lowest tiered beds and if he goes to bed at around 23-00 with low energy he is full energy at around 3. Is it possible to alter this somehow using the relativity mod. I’m still looking around the features but can’t really find anything.

NRaas > Relativity > Motive Delta Factors > Energy > (set the factor to some value less than 1, such as 0.5 to start out) and take note of the impact.
