Hi,
Although vitamins never hurt you, to my experience reducing stress levels is key for improving sleeping. Also offcourse make sure you don’t take caffeine, alcohol or sugar in the evening. Develop a steady sleep routine. Preferably no phone screen but just reading a book before sleep. Also meditation (like the headspace app) can help.
I’m happy my sleep got better after a the first two weeks. During that short period I had nights with only a couple hours of sleep. I quickly got this (Dutch) self help book from a tinnitus expert. A clinical neurodoctor that specializes in tinnitus distress. He explained the vicious cirkel of tinnitus, stress, anxiety, insomnia, etc. This is known as the tinnitus syndrome (or tinnitus complex). To break this cycle you have to lower stress levels. Do activities you like, take enough breaks, etc. If really needed short term sleeping drugs or anti-depressants can also be used. After I explained the situation at work, I could cut down my working hours temporarily. This gave me room to relax more, go to bed extra early and meditate. The lower stress level quickly improved my sleep. I now manage to sleep from about 22:00 till 5:00-6:00. Sometimes its much shorter, but those nights are less frequent and correlated to a more stressful day. I’m confident my sleep will improve further as my stress about tinnitus gets down further. Which is a tall order as you all know. Also I think it can work counterproductive to focus to much on sleep. You can’t force yourself to sleep. Just relax and see what happens. One or two nights of bad sleep will not knock you down. Know these are just exceptions. I have three young kids that kept us up for months in a row. Eventually we got back up.
Happy to exchanges advice about this topic.
