I think doing my own work comes out a little on top, but I do enjoy the classes as well, although at the moment most of the people who come know what they are doing and I sometimes feel a bit superfluous.
My practice would not let me book a meds review with a GP it would have to be with the practice nurse and there is no point in that. The meeting with the MH nurse will be a sort of review, she actually has as much power as the GP's and can prescribe and refer as needed.
