I've wrestled with insomnia on and off since high school. It's almost always anxiety-related and I've tried everything from Tylenol PM and Benadryl to Lunesta and Ambien . Even with the Lunesta and Ambien, sometimes they work, but sometimes they don't and my mind is able to fight them off. I've learned to live insomnia and like I said, sometimes I'll fall asleep and sometimes I won't. I'm getting married in a few months and really want to be able to have guaranteed sleep the night before the wedding. I already know it's likely I'll have insomnia since I'll be so keyed up. For this one night, are there any drugs out there that can literally "knock you out"? Again, I'm not looking for something long-term or that would be used habitually, but just something really strong that could be used one time? Thanks so much!
