Hi, I've been using a sleep machine for about 3 years now. it's my pacifier-i'm hooked on it now. If by chance it goes off during the night, I automaticaly wake up. I started using it to help drown out any dog barks that I might here. I'm a very light sleeper and I wake up very easily, unfornunetly. sorry, if my spelling is off-my first time using a computer for typing. I always keep a extra sound maching incase the one I'm using stops working. I like the rain noise the best - its the most soothing. Forget the waves sound, or God forbid; tropical animals calling in the jungle!!! Just what I need.
