I don't know why you had hives, but I'm pretty sure it wasn't the antiperspirant. I agree with the dermatologist that Drysol makes sense. I really think you are risking nothing by trying it. And it is true that practically all antiperspirants containing aluminum chloride.
As to Zoloft withdrawal, I doubt any connection. Sweating begins at different times in different people, for no special reason. No need to suffer with it, though.
Best.

Any suggestion I feels as if I look five years older than I am. Please help.
