bethers,
Well, I was on xanax for roughly 10 years. I started out taking .25 mg 2-3 times a day. After a while, my Dr. upped my dosage to .5 mg 2 times a day. I took .5 mg for about 2 to 3 years. When I quit taking my xanax, I cut it back to 1 pill a day for about a week, then discontinued it altogether. I was also taking 150 mg of Effexor and decreased that to 75 mg per my Dr.'s advice. I had some side effects with that, but none with the xanax. I think you should be fine since you upped the zoloft. Also, try not to think about not taking the xanax, it does help!!!
