Why stop taking it, has the GP given any reason?
Any medication needs careful weaning, it took me 9 weeks to get off one AD with GP support. He had access to smaller amounts for exactly that purpose. What I found was, that after 48 hours, any withdrawal feelings (which were awful ) stopped; I reduced every 3rd or 5th day and took it slowly. My brain kept telling me that I would have to re-start but with support I got there!
