I take it are quitting ambien? While ambien withdrawal is extremely annoying it is fortunately fairly short (2-4 days usually). Now you should probably drink some warm tea and read a book or whatever you do to relax. Herbal supplements (melatonin and valerian root for example) help a lot too. Remember that it only lasts couple of days. Don't take ambien under any circumstance or the withdrawal will just last longer.
