ADHD helped more at 150 or 300? Sleep?

I'm on 150 and it's helped my ADHD a decent amount. I also cant sleep. I'm considering moving up to 300, but..... id like to sleep.

has anyone increased and not had *worse* insomnia?

has anyone switched to night time dose after having insomnia, and had good luck? I feel like it would keep me up more..... thanks!
