I have been on it for about 16 months now, and take 125mg. I don't specifically remember having any issues with waking up in the middle of the night, but I had terrible sleep problems prior to starting it anyway. I can say that for me, most side effects went away after the first few months of taking it. Good luck to you both and I hope it works for your pain as well as it has worked for mine!
