I would continue taking anything that is not making you feel well. How long have you been seeing him prior to this? Long enough for him to be familiar with your situation? If you are serious about SSI, which it sounds that you are, you should definitely keep all of your appointments and do exactly what you need to do in order for him to write the report-- however that does not include feeling like you have to take a medication that is making you uncomfortable. I hope you can discuss this with him. Good luck at your appointment.
