Ambien 10 mg tablet is advised to consume right before going to bed to achieve the best results in the body, as its effectiveness may be reduced if taken along with food or right after eating. Some common side effects of Ambien are headache, dizziness, tiredness, and feeling of sickness. Misuse of Ambien can result in addiction, overdose, or even death, particularly when combined with alcohol or other substances that depress the central nervous system.
