That's not good. Can you please try to set debug to 1 in RSE's ini file. Then go to sleep, and after having waked up, open the console and report all console messages after then one saying something like "Planning to sleep at..." If you can provide me that, I will at least have a chance to find out what's happening. But I can try to test a bit here too.
The console output is (less the prefixes):
Planning to sleep at 209
optimal wake is 16.3
Been awake for 48.77. Optimal is 16.32 Tiredness is 32.00
attribute decrease is 0.3200 of each individual attribute
The ini file is included below

set RSE.minWake to 6
; The additional number of hours a player with 100 Endurance can go without sleep. Default 20
set RSE.enduranceFactor to 24
; Thus a player with 50 Endurance can go minWake + enduranceFactor * 0.5 = 18h if using default settings

; 1 means that all attributes will decrease for each hour of tiredness. 0 disbales this and enables percentageDecrease instead. Default 0
set RSE.attributeDecrease to 0
; percentageDecrease is the decrease in % of each attribute per hour of tiredness. If Strength is 60, a value of 0.75 means that Strenght
; will decrease by 60 * 0.75 / 100 = 0.45 per hr of tiredness - almost one per 2 hr of tiredness.
; This setting is ignored if attributeDecrease is non-zero. Default 0.75
