I've completed the low-and-slow switch from Citalopram 40 mg, which I've been taking for 11 years, to Zoloft (sertraline) I just increased the dose from 25mg to 50 mg, which I plan to continue until I talk, to my physician at the end of the month. It feels like it is working well so far with anxiety level pretty well controlled. No side effects. One of the reasons my physician switched to Zoloft was its wide dosing range, which allows increases as needed to the max dose
