I have been on Fluoxetine for 12 years now, as I had a complete breakdown after my first shunt, which was due to alot of factors which we are all familiar with. When I went to have my first LP shunt to prevent total blindness, I also had to deal with problems at work, at home, with friends and family because they didn't understand, and were less than sympathetic. I was also told my sight would return to normal so my expectations were high, but it didn't and I was left with no peripheral vision and no depth perception.
Although it took me a couple of years to fully recover, my Doctor has kept me on it, I suppose as a precaution, especially after having so many surgeries in the space of 2 years.
