"i was ok with prozac for years until i hit &quot;prozac-poop-out&quot;.  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&#039;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!"
