I have had insomnia problems but eventually overcame them. People can become addicted to zolpidem, the generic for Ambien. Ambien does nothing for me as I quickly get used to it, but long-term use such as yours can lead to addiction. The recommendation is a gradual tapering off over weeks. Trazodone needs much higher doses than other medicines. Usually Trazodone is prescribed in 100 mg. for sedative effect. I got hooked on benzodiazipines the doctor prescribed and only dropping .5 of a mg. after being on it for only 4 weeks caused my insomnia. It took many weeks of little sleep to get back to normal. I'm still taking 1.5 mg. Hope this gives you some insight and ideas to discuss with your doctor. If all else fails, the body does get so tired that you will eventually sleep. Just do not worry about not sleeping, but accept that you are not sleeping and let time take you into sleep.
