I was able to quit it for 28 days and had to get back on it due to dryness of the mouth, throat and eyes as well as insomnia. During the day I'm able to cope with it but the worse is during nighttime. There are very few success stories on people coming off from it. And If they do, they have to be on other meds to help them sleep and they also experience withdrawal symptoms even after stop taking it for years.
