I was pretty much a walking zombie due to no sleep. The stress and fatigue were killing me. I would finally fall asleep when exhausted only to wake in an hour or so. I had to drug myself. Then I started to stress about taking sleep drugs.
At the present time I sleep with earphones with masking sounds ("sound enrichment") all night and I take about 2 mg of Ambien to get myself to fall asleep. I used to take an additional 2 mg at 2am if I woke up but that doesn't happen anymore. My doc tells me not to stress about taking the small amount of Ambien so I don't anymore. Not like I have a choice though. I tried several other drugs and settled on Ambien because of the minimal side effects for me. Some nights I can sleep without the Ambien but not often.
I'm so used to the earphones now that I probably would continue to wear them even if the tinnitus vanish. I actually like wearing them now. They block out noise that would otherwise disturb my sleep. I don't ever take a nap. I try to be really tired when I go to bed and get up when I awaken in the morning.
I don't like to recommend taking drugs to sleep, I wouldn't if I didn't have to, but it saved me. Good luck.
