Got an appointment wu an OH nurse tomorrow, unclear if it's to talk about mh (as I had an interview about that over the phone), it could be the vaccinations I need instead perhaps. How long might this appointment last? As I am viewing flats after and it's going to be really tight getting my train home at this rate! Please note that I've had this condition for about 8 years and have been stable for over 4, with no real side effects. Please say it'll be less than an hour!
