They work for some people. Maybe 30%? But they all have significant side effects. One neurologist I went to said he could prescribe me one of two. “One will make you fat and the other will make you stupid” was what he told me. I was in grad school so I told him I could deal with weight but I needed my brain. He told me I would be surprised how many people made the opposite choice.

In the end the one I tried didn’t work for me anyway...
