I have taken Lunesta

I have taken Lunesta, as needed, for several years. Now not very often at all. Sleep great. No more nightmares. I only take 1/2 mg per night and that is plenty. I drink water after taking the tab and the aftertaste is gone. If any lingers, I eat a small something, like bread or cracker and it is gone. Solved a life long sleep problem for me. Age 69, so I appreciate it
