Glutamate and Trouble Sleeping

So I’ve been dealing with some insomnia and general restlessness the past number of months. Been researching like mad and trying to figure out what might be causing this for me. I read that excess glutamate can cause this and a lot of dairy foods have glutamate. Well one of my staple proteins is non fat Greek yogurt and to a lesser extent cottage cheese. I eat a lot of this stuff. Does anyone know if these foods are on the higher end of glutamate content? Any advice is appreciated. Thx

Try cutting it out. See what happens.

It’s hard to avoid.

What brought you to this conclusion?

I just came across a few pages where it said that cultured foods such as yogurt and some cheeses have high amounts of glutamate. And like I said, I eat a lot of the stuff
