Sleep medications have the potential to relax the brain and the central nervous system for a quiet rest at night. Patients suffering from insomnia and other sleep disorders take them when they experience sleepless nights in bed. Sleeping pills over the counter are the best alternative for insomnia patients who stay awake at night and struggle hard to get back to sleep. However, studies have shown that these medications have addictive qualities and their prolonged use can make the user addictive and dependent.
