I'm not sure what specialty to choose. Here are some of my problems. I'm forgetting more and more. I sometimes smell cigarette smoke (at home, at school, etc.) when there is no one smoking. I sometimes have problems with my equilibrium. Also, I have been very lethargic (I do have a bit of a cold though). I have a doctors appointment set up in mid-March, but just wanted to check and see if I should go sooner.
