★★★★☆
I too have suffered with tinnitus since developing Ulcerative Colitis (IBD) over 12yrs ago. I suddenly realised a few yrs back that when my anaemia is worse, so is the tinnitus & vice-versa.
I do have a white-noise maker but its quite uncomfortable to wear for 8hrs p/day (I have small ears lol).
I can't tolerate a lot of iron (had large bowel removed) so I take it in a multi-vit AM & take a 14mg ferrous sulphate or 2 straight after my evening meal. This keeps it quieter.
