Zoloft was my miracle drug. It definitely helped me get my life back together. But, unfortunately, 4 years on the max dose (200mg) and my body got used to its affect on me. I was sad to tell it goodbye.
Of course, everybody's body is different. I may be wrong, but 25mg seems a little to low of a dose to be able to tell anything. I certainly couldn't tell a difference on 25mg. But if it is what's causing you to feel awful, then I hope you are able to find the right med for you
Good luck, dear
