I mentioned this in a former post about zanaflex and was wondering if anyone else noticed this happening. I usually take 4 mg of zanaflex before bed and specifically take notice of when I'm just falling asleep (or have someone take note of the time i fall asleep). I always wake up exactly 2 hours later, almost to the minute. I wondered if anyone else had this problem? Do I maybe need to increase my dose? Even if I just take 2mg, the same thing happens. It is the best muscle relaxer I have taken, but I can't get back to sleep after I am jolted awake the 2 hours later.
