Every time I read, text, or spend time on my laptop I inevitably doze off! After just a few minutes my eyes get heavy and my vision blurs, and repeatedly have dozed off, causing my head to do that jerk awake thing. I'm on Ms Contin, oxycodone-acetametaphine, paxil, elavil, lisinapril, flexaril, those are my main meds. Is it caused by any of those? Or is it something I need to have checked out? My eyes are really heavy as I'm writing this to you!
