There was a virus going around here that lasted a long time like that too. I haven't heard of anything lately. But a lot of my coworkers had it. I had gotten a flu shot and haven't caught anything as of yet. Hopefully wont. But last year I did have a bout of brohchitis in the spring and a virus. But the shot usually covers me throughout the most of the winter.
I hope that you feel better soon. I started taking abilify about a year ago and still have good results from it. I hope that if the zoloft doesn't work for you that the abilify does.
Best wishes,
Hugs, Karen
