If my sleep gets interrupted by an emergency will this make me so groggy I can’t respond?

Great question. Usually people respond great so it shouldn’t be an issue; plus, there is  nothing in there that’s medicinal. Now, anytime you are in a good deep sleep it may take a bit to freshen up but that’s the beauty of Relax. The quality of sleep is enhanced so even if the quantity isn’t there you’ll get the most bang for your buck so to speak.
