For several weeks I've felt drowsy throughout the day. I'm dozing off watching TV, in the movies, in yoga and even fighting to stay awake driving. I get plenty of sleep. I'm wondering if I'm deficient in something. Any thoughts?
Are you just feeling tired or have you gotten a cancer diagnosis in the past and are feeling these symptoms?
I would go ahead and visit the doctor- it could be that you are anemic, have low vitamin B- or really anything else. It's worth getting some blood tests done and seeing what's up.
