@Shunda sertraline x
My partner is on them and he's been struggling to finish, he sometimes does struggle and sometimes he is able to but they have said there is another tablet that they can switch it too which can help, I'm unsure if it is the same for Women but it's worth going back to the Dr and asking to switch tablets as they should ask you at your medication review anyways.
I had the same issue and if I could it was tiny and I lost all my sex drive, but not sure if it was the meds or the unhappy marriage!
Which ones are you on?
