Okay so here is the deal. I have three types of tinnitus: 1. One caused by an anti-depressant 2. One caused by accoustic damage 3. Increased intensity due to long term benzo use (have been able to lower that more often lately. The previous 2 I have not been able to get rid of. Neither of them is maskable. I was reading a site where a guy says he got ringing from an SSRI anti depressant call Celexa which is a very similar drug that I took that gave me ringing.

I hate that feeling. Not sure if I would get it or not. Also, the possible feeling of foggy thinking. If these would go away quickly, I might be okay with it. Secondly, I would have to find a way to get my doctor to prescribe it for me due to it being labeled for Alzheimer's disease. Thirdly, I do not know what the long term consequences of the drug if it works. Finally, I don't know if it would even work or worse, it might mess me up on the first dose! Thoughts? P.S.- Please forgive any grammar errors. I am very tired right now.
