Grasping at straws again, UB. You don't know that Z was taking temazepam on that night. The side effects you mention are rare according to your wikipedia link, less that 0.5%:
"
[h=2]Adverse effects[/h] [h=3]Common[/h] Side effects typical of hypnotic benzodiazepines are related to
CNS depression, and include
somnolence,
dizziness,
fatigue,
ataxia,
headache,
lethargy, impairment of
memory and
learning, longer
reaction time and impairment of motor functions (including
coordination problems),[SUP]
[13][/SUP] slurred speech, decreased physical performance, numbed emotions, reduced alertness, muscle weakness, blurred vision (in higher doses), and inattention.
Euphoria was rarely reported with the use of temazepam. According to the
FDA, temazepam had an incidence of euphoria of 1.5%, much more rarely reported than
headaches and
diarrhea.[SUP]
[12][/SUP]
Anterograde amnesia may also develop, as may
respiratory depression in higher doses.
[h=3]Less common[/h]
Hyperhydrosis,
hypotension, burning eyes, changes in
libido, hallucinations, faintness,
nystagmus,
vomiting,
pruritus, gastrointestinal disturbances, nightmares,
palpitation and paradoxical reactions including restlessness, aggression, violence, overstimulation and agitation have been reported, but are rare (less than 0.5%).
Before taking temazepam, one should ensure that at least 8 hours are available to dedicate to sleep. Failing to do so can increase the side effects of the drug.
The use of this drug in combination with alcohol potentiates the side effects, and can lead to
toxicity and
death.
Though rare, residual "
hangover" effects after nighttime administration of temazepam such as sleepiness, impaired psychomotor and
cognitive functions may persist into the next day, which may impair the ability of users to drive safely or may increase the risks of falls and
hip fractures.[SUP]
