Hi I want to let you know I have been where you are,and not to long ago. First i want to say that Buspar is not an SSRI like zoloft is,it is a whole different medication. Secondly if you are taking xanax do you take it as needed or are you on a steady dose? when i started zoloft i was able to start at 25mg,but thats me,I have med phobia also,but it was when I reached 50mgs i had my problems and the ones you are describing ,some of the symptoms you are experiencing are not from the zoloft it is heightening your anxiety,which I have been told is a good sign,meaning it will probably work for your anxiety in the long run.I have to up my dosage very slowly,i did 25mg for 2 weeks,then i took a 25mg plus half a 25mg for 2 weeks,then went to 50mg as i said this is where i got my symptoms,scary yes ,they drove me wild,first 9 days were hardest,and I was taking ativan 1mg 3 x's a day,it lessened my anxiety but did not take care of all of it and have had many doctors say the benzos may just not take it all away. If you feel your better off starting slow than do so tell your doc you want to start at half of a 25mg,do it for 2 weeks if you feel good than go up,if not hold for another week I held at 50mg for 3 weeks,than took 50mg plus half of a 25mg and was okay,in my opinon it is much better to work with an SSri or an SNRI ,versus taking the benzos in your case the xanax if you have been taking it for awhile than the zoloft may help you even better so you wont have to take the xanax,or ask your doctor to prescribe a longer acting benzo such as ativan or klonopin to get you over this hump, I would give the zoloft a fair shot I to wanted to stop,but with the help of the forum here and a specific person I stuck it out ,its been i think almost 10 weeks now and i am only up to 75mg,on tues i will go up to 87.5mg that will be a 50mg breaking a 50mg and breaking a 25mg,my goal is to reach 100mgs,it has helped me my depression is gone and i am now tapering off the benzo which will be slow also,i was on zoloft before from 2003-feb 2010 i didnt taper it I just stopped taking it and i was fine i had been on it for PMDD and i had no problems going on it but it was being used for something different but I also dont recommend doing that as my circumstances were different than,and that was me not you,now i do take it for anxiety,and i do therapy which is also a very crucial part in all this i dont know what you have been reading but it is a good idea not to do that,you are not those other people, but having good communication with your doc is good,let them know how you feel and what you think might be best for you,they work for you,so express yourself,tell them what you want to try even if it means going slower,and/or switching benzos,advocate for yourself and be good at it. give it a fair shot i think you might be impressed with the results, you dont have to be on zoloft forever some doctors let ya do 6 months or 1 year some people need it longer,it just depends,I dont know what else i can say about zoloft and how its helped me this far but if you can hang in there i would,keep us updated on what you decide.
