Your habits just before going to bed could be sabotaging your sleep.

The National Sleep Foundation recommends avoiding the following: over-the-counter medications that contain pseudoephedrine, which can be found in common cold medicines; texting, watching TV, or spending time on the computer shortly before bed; indulging in a greasy, fattening, salty bedtime snack, which can be stimulating and trigger nightmares; and drinking caffeine beyond the morning, as it can stay in your system for as long as twelve hours.
