Once I realised I was starting to get quiet days I kept diary notes.
First three weeks I have had 4 very quiet days and three quite quiet days so that's 7 days out of 21 that I have had none or negligible tinnitus. This is after years of constant noise.
No patern to do with food and drink but I have noticed that the quiet days seem to coincide with 'special' days, ie: birthdays or other big days.
I have a hunch that having absolutely no alcohol makes it worse but as I don't want to encourage boozing take that with a pinch of salt.
