I don't know if anyone is following my posts on Ginkgo, but if there be...
Once a week I take 3 x 30mg the day before I would like a guaranteed (?) break from tinnitus for a few hours the afternoon of the following day. It didn't happen yesterday. Instead, it happened today. T in the morning (as usual) this Thursday and I expect it to come back in the evening. Perhaps the chilled air I was out and about in on Wednesday had something to do with the delay.
I might add that compared to some I've read of on this site, my T is definitely on the milder side. No health issues that might have caused it, or ear damage from loudness. It came to me aged 63.
