A lot of these same symptoms are what I have every day, without abusing any meds -- prescription or otherwise. Taken from The Dallas Morning News, June 3, 2003: "TELLTALE SIGNS FOR OFFICERS" Dallas police officers who become drug-recognition experts complete 156 hours of training and must be certified every two years. To determine whether a motorist is under the influence of drugs, the officers follow a 12-step standardized test. They are taught to look for the characteristic effects of the following drug categories: • Stimulants, such as amphetamines and methamphetamines – dilated pupils, elevated vital signs and agitated movements. • PCP – dilated pupils, elevated vital signs and distinctive horizontal and vertical eye movement under testing. Also rigid muscles, a blank stare, an absence of pain and reports of hallucinations. • Hallucinogens, including LSD and ecstasy – constricted pupils, elevated vital signs and distorted sensory perceptions. • Cannabis, such as marijuana and hashish – impaired depth perception and an inability to maintain attention. Also causes an accelerated heart rate, muscle tremors and forgetfulness. • Narcotic analgesics, including opiates such as heroin and morphine – constricted pupils, depressed vital signs, forgetfulness and slow and deliberate movements. • Depressants, including alcohol, barbiturates and tranquilizers – relaxed muscles, drowsiness, impaired balance, slurred speech, depressed vital signs and distinctive eye movements. • Inhalants, including volatile solvents, aerosols and anesthetic gases – specific chemical odor and residue on the user's face or clothing. Impaired walk, slurred speech, accelerated heart rate, increased pupil size and distinctive eye movements.

Of course, if I feel under the weather, I let someone else do the driving.
