10Medications
A number of OTC medications and drugs would cause insomnia in many people. These include weight-loss products, decongestants, antidepressants, blood pressure, and heart medicines, allergy medicines, and pain medications, which might contain some stimulants such as caffeine. Taking these drugs could disrupt your REM sleep, block the production of melatonin, and tamper the natural levels of enzymes and pathways in your body. While antihistamines might make you feel drowsy at first, they could result in regular urination and disturb your sleep pattern later. Thus, make sure to read the labels carefully and ask your doctor for advice. [10]
