Prozac stopped me from ruminating. It happened like the first day i took it, which ive been told is not a usual response and is indicative of a different mental problem. I dont care, im just happy it stopped. Now (or in recent times) when i am with my mother, i can tell SHE is doing it,and i feel like i am running away from a runaway lawnmower! But i used to be right there with her.
