Ativan and zoloft

Im still on the fence about Ativan...I am taking a 1mg tab once a day along with my 100mg og zoloft. The ativan is for my dystonia, which is a result of certain surgeries i had to rid myself of cancer. The dystonia would flare up and become horrible (meaning my neck,left shoulder and left side of my back would twitch like crazy)and this eventually lead to the ligaments in my shoulder becoming so loose from the twitching that I have had to have two more surgeries to correct that problem. Since taking the ativan on a daily basis, I have has almost NO ticks or twitches. however, while i don't have as much anxiety, i do feel more depressed and my doctor upped my zoloft...
