Welcome to the forum. I'm sorry you have been struggling with your sleep for 7 years! I have insomnia too and it has effected my everyday life. Among other physical disabilities, constant lack of sleep has caused me to be unable to focus and my short term memory is shot. It's a downward spiral, but I try to make the best of it.
