Problems with sleep can certainly make you feel like you are losing your mind, and if you have mental problems, lack of sleep worsens them.

I use Lunesta and Trazodone to sleep but even if I take my max dose, I often cannot fall asleep. And when I wake up, my eyes feel sore as if I was laying with them open for those several hours.

Sometimes I sleep too much though.

Supposedly there are ways to get back to sleep but the only thing that has worked for me is to binge on carb loaded sweets.
