no you can't carry a full sized blanket to work. How about looking for a sweater in you favorite comforters type of fabric and design. that way you can still wear your "comforter" item at work. One time I actually cut down a comforter into a shawl and wore it at work. I had requests up the you know what in orders to make more for my co workers.

My back pack ALWAYS has something in it from home - a doll or bean bag ( the kind that smell good and go over your eyes for relaxation but I rub the material and beads) my favorite pillow case that goes with my flannel blue sky and clouds comforter set, a teddy bear. you name it one or two items always find there way along for the trip.

Yes talk to your doctor about the meds to.
