I went from 80 to 120 a week ago and didn't notice a difference. I take it at night an hour before bed because it is sedating for several hours.

But I didn't notice a difference at all during the next morning or following day.

I used to have insomnia on it so I took a low dose of Seroquel for about 6 months. It seemed to resolve on its own because I'm off Seroquel now.
