I would imagine almost all of people who have this constant and severe. It's almost a given.
Before tinnitus I never had a bad night's sleep in my life. I could sleep standing up. Now I wake up ten times a night. Everyday I feel like a zombie and it's getting worse. A few months ago I was just about coping and working but now my body is falling apart with exhaustion and I'm ill constantly.
Before I got tinnitus I didn't even have a cold for about 5 years. Since I got this 18 months ago I've been hospitalised with exhaustion, pneumonia, kidney infection and multiple chest infections and flu like symptoms. I even got hives recently after not sleeping for three days in the midst of my latest illness.
This affliction, at its most severe, opens a doorway to hell. No human is designed to be able to endure this.
