Ambien is a medication that can help you relax and unwind before bed. It is a prescription sleep aid that works by increasing the activity of a neurotransmitter called GABA. GABA has a calming effect on the brain and helps to promote sleep. Ambien is typically taken at bedtime and starts working within 15-30 minutes. It lasts for about 4-6 hours. Ambien can be an effective way to relax and unwind before bed, but it is important to note that it can have side effects, such as dizziness, drowsiness, and amnesia. It is also important to follow your doctor's instructions carefully when taking Ambien. Buy Ambien online without RX in USA Overnight.
