Supplement overdose

One year ago, in an attempt to improve my post-Propecia state, I started using Brewer’s Yeast, and on some day I took 5 tablets during that day (the maximum dosage on the label), along with 1 tablet of Glutamin and maybe some other amino acid.
Then at some point I took a nap, only to wake up after an hour to strong head tremblings (felt like an earthquake) and since that day until this moment, I suffer from a vertigo like feeling, which accompanies me whenever I walk and when I lie down.
So after this my daily life had become truly intolerable.

I went to two neurologists - one of them prescribed me Agiserc (which didn’t really help), and the other said It’s not understandable why I suffer from this. Both of them was skeptic about the supplements as a factor.

Did/Does someone else on this forum suffer from the same issue?

I’ve had these from time to time but usually in conjunction with bad food. You might have gotten a yeast infection. Brewers yeast didnt agree with me either. No advice really except tio see if you have a yeast infection and cut out sugar…
