- decreased performance
- decreased quality of daytime sleep
what two stimulants can be used to increase alertness for night shifts

increased risk for depression and other disorders

selegiline
what is known as ‘liquid exstacy;
hydroxybutyrate
what is restless leg syndrome
parestheisas felt deep in the calf muscle with the urge to move limb
what are two common physiological causes of RLS
- low dopamine levels in hypothalamic cells
