I tried serc for one month in the beginning days. Helped little and me very drowsy. Again I tried few years ago and it made me very sleepy and worsened my symptoms
I learnt to ignore tinnitus now. It is always on my left side. Only in quiet settings it gets very much amplified ofcourse

Xanax brings down the tinnitus too but tinnitus is not an issue for me anymore. Atleast at this point.
I don't like drinking alcohol so thought I try marijuana. Looks like didn't work for you. As I said I really don't want to take any of this stuff.
But right now I am in a desperate situation. 6+ years daily head pressure headaches, dizziness, fatigue etc., Took a toll on my body and brain. No permanent solution and all temporary. I did my best to get out and do things and at times push it too. Not sure how long I can lead this terrible life.
