I've had a kind of jittery teeth grinding effect ever since I started taking simvastatin a few months ago, and I noticed it was keeping me awake.
I started taking it mid day so I could get a nights sleep.
I mentioned it to my endo and he said that sleep problems weren't a noted side effect of simvastatin and that it must be taken at night. Otherwise he seemed fairly disinterested.
If I take it right before bed as instructed, I'll drop off, but then be gradually awoken 1-2 hours into the night until I have to resign myself to the fact that I'm absolutely wide awake and I'll have to wait it out.
I googled it tonight, as it's 3am and I'm unable to sleep again and it turned up all manner of things regarding simvastatin and insomnia.
Does it effect anyone else like this?
