Clonazepam is the prime suspect for my excessive daytime sleepiness. I also experience frequent mild nausea. As it's usually mild, I no longer bother much with the nausea. When the nausea is more than mild, I've taken to eating bits of raw ginger root.

If I could get along without Clonazepam, I would. As it is, it's the lesser of the optional evils.

Oh, I find sleep is important for everything else. Can you time your meds to maximize a positive effect on your sleep?
