I'm not quite sure on what effects this has on aiding or preventing sleep. I know that most of my life I've had great difficulty sleeping but I've also been drinking hot chocolate before bed almost every night out of habit (for roughly ten years, I'm 15 now). Could the two possibly be linked? I don't mean to be a bit paranoid but I keep getting a little worried that it could have had some long term effect. I keep getting relatives telling me it was not wise to drink milk just before bed, but this is what I've been doing for years. Please can someone justify what the effects are because I'm a bit worried.
