insomnia
"I've been on Lunesta for 5 years.  Horrible to be an insomniac for this long.  Tried Belsomra over the last four days and it's pretty amazing.  You take it an hour before bedtime and you have to be in a mental state of letting go of your fear of not sleeping, in order for this to work.  It gets me to a drowsy, sleepy mode.  The issue is that I keep waking up throughout the night and am waking up super early so while it's solid on sleep initiation, I don't know why I can't stay asleep.  But having said all of this, I'm pretty impressed with how I feel on only 4-5 hours of sleep.  It seems as though even though I'm waking up periodically, I must be getting higher quality sleep than on the other drugs.  Overall, I'm quite optimistic."
