Have your doctor check the dosages and types of any meds you might be on, Bob. They could be causing drowsiness and/or need to be changed, BUT don't do anything without checking with your doc first! Also, do you sleep well? If not, you should have your oxygen satuaration rate checked to rule out sleep apnea. Depression can bring about sleepiness, from what I've experienced and seen in others.

Good luck,
