depression
"I was OK with Prozac for years until I hit "Prozac-poop-out".  I then took Wellbutrin for several years and it was great... Until my insurance switched to the generic in June 2009, and it suddenly quit working.  I had no idea of the switch until I started researching for something else that might actually work again and discovered the generic issue.  I asked to be put back on the real thing, but the most my insurance was willing to do was to switch to a different generic manufacturer = marginally better.  The insurance co. is throwing away money on generics that don't work!  I am going to try again to get back on real Wellbutrin XL even though it will cost me quite a bit more -- it will be worth every penny!"
