Sleeplessness is one of the major causes of impaired cognitive function and poor health. Insomnia patients remain drowsy during the daytime, suffer from mood swings and find it difficult to concentrate on any topic. Inadequate sleep makes them prone to obesity, hypertension and diabetes. People experiencing sleepless nights mostly resort to natural sleep aids in order to doze off at night. If natural remedies and change in lifestyle don’t allow people to doze off, then they can rely on a non-benzodiazepine sleep medication called Zopiclone to attain a calm rest at night. It not only lengthens the duration of sleep but also improves its quality. Doctor’s ask their patients to take this pill in a short duration in order to avoid dependence. Cases of addiction and tolerance have been reported from those who took this medication for more than a month. Mild side effects such as dizziness, headache, nausea and dry mouth usually go away after a week. Serious side effects such as aggression, hallucination and nightmares should not be taken lightly and must be reported to a physician. Zopiclone shows better results when combined with better sleep hygiene and natural sleep aids. Sleep deprived patients can buy Zopiclone over the counter in the UK to restore their circadian rhythm.
