Having insomnia is very unpleasant and it leads to fear of having it again the next night. My pattern is that I have one sleepless night, so then the next night I take 1/4 dose of the sleep med and I will take it for several days in a row until I think I will sleep again. During the stress I have been under the past three years, I believe I took the sleep med every night for a good solid year. I am happy that I have cut back to just randomly taking it.
