Well, the medical required for a F/W license is the same one for helicopters (although as we all know helis require FAR more skill!) so get yourself to a AME and ask for a class 2. Obviously its up to him/her whether or not you're fit - and obviously if you're a complete nutter you shouldn't get it. If not, you should, and best of luck to you. Shell out $100 and you'll have the answer to your question.
