I have had the worst flare up for five years. I am taking pregabalin 75 x 3 morning and night and they have stopped working, I've got such a rotund stomach that when I get into bed I am finding it hard to breathe the weight gain has been unbelievable since starting pregabalin. I read somwhere about duloxetine and I want to talk to my doc about them. Where can I find information that had been varified? All help taken on board.
